-# Plan: Implement Missing Async Functionality in SharpCompress
-
-SharpCompress has async support for low-level stream operations and Reader/Writer APIs, but critical entry points (Archive.Open, factory methods, initialization) remain synchronous. This plan adds async overloads for all user-facing I/O operations and fixes existing async bugs, enabling full end-to-end async workflows.
-
-## Steps
-
-1. **Add async factory methods** to [ArchiveFactory.cs](src/SharpCompress/Factories/ArchiveFactory.cs), [ReaderFactory.cs](src/SharpCompress/Factories/ReaderFactory.cs), and [WriterFactory.cs](src/SharpCompress/Factories/WriterFactory.cs) with `OpenAsync` and `CreateAsync` overloads accepting `CancellationToken`
-
-2. **Implement async Open methods** on concrete archive types ([ZipArchive.cs](src/SharpCompress/Archives/Zip/ZipArchive.cs), [TarArchive.cs](src/SharpCompress/Archives/Tar/TarArchive.cs), [RarArchive.cs](src/SharpCompress/Archives/Rar/RarArchive.cs), [GZipArchive.cs](src/SharpCompress/Archives/GZip/GZipArchive.cs), [SevenZipArchive.cs](src/SharpCompress/Archives/SevenZip/SevenZipArchive.cs)) and reader types ([ZipReader.cs](src/SharpCompress/Readers/Zip/ZipReader.cs), [TarReader.cs](src/SharpCompress/Readers/Tar/TarReader.cs), etc.)
-
-3. **Convert archive initialization logic to async** including header reading, volume loading, and format signature detection across archive constructors and internal initialization methods
-
-4. **Fix LZMA decoder async bugs** in [LzmaStream.cs](src/SharpCompress/Compressors/LZMA/LzmaStream.cs), [Decoder.cs](src/SharpCompress/Compressors/LZMA/Decoder.cs), and [OutWindow.cs](src/SharpCompress/Compressors/LZMA/OutWindow.cs) to enable true async 7Zip support and remove `NonDisposingStream` workaround
-
-5. **Complete Rar async implementation** by converting `UnpackV2017` methods to async in [UnpackV2017.cs](src/SharpCompress/Compressors/Rar/UnpackV2017.cs) and updating Rar20 decompression
-
-6. **Add comprehensive async tests** covering all new async entry points, cancellation scenarios, and concurrent operations across all archive formats in test files
-
-## Further Considerations
-
-1. **Breaking changes** - Should new async methods be added alongside existing sync methods (non-breaking), or should sync methods eventually be deprecated? Recommend additive approach for backward compatibility.
-
-2. **Performance impact** - Header parsing for formats like Zip/Tar is often small; consider whether truly async parsing adds value vs sync parsing wrapped in Task, or make it conditional based on stream type (network vs file).
-
-3. **7Zip complexity** - The LZMA async bug fix (Step 4) may be challenging due to state management in the decoder; consider whether to scope it separately or implement a simpler workaround that maintains correctness.

-# Plan: Modernize SharpCompress Public API
-
-Based on comprehensive analysis, the API has several inconsistencies around factory patterns, async support, format capabilities, and options classes. Most improvements can be done incrementally without breaking changes.
-
-## Steps
-
-1. **Standardize factory patterns** by deprecating format-specific static `Open` methods in [Archives/Zip/ZipArchive.cs](src/SharpCompress/Archives/Zip/ZipArchive.cs), [Archives/Tar/TarArchive.cs](src/SharpCompress/Archives/Tar/TarArchive.cs), etc. in favor of centralized [Factories/ArchiveFactory.cs](src/SharpCompress/Factories/ArchiveFactory.cs)
-
-2. **Complete async implementation** in [Writers/Zip/ZipWriter.cs](src/SharpCompress/Writers/Zip/ZipWriter.cs) and other writers that currently use sync-over-async, implementing true async I/O throughout the writer hierarchy
-
-3. **Unify options classes** by making [Common/ExtractionOptions.cs](src/SharpCompress/Common/ExtractionOptions.cs) inherit from `OptionsBase` and adding progress reporting to extraction methods consistently
-
-4. **Clarify GZip semantics** in [Archives/GZip/GZipArchive.cs](src/SharpCompress/Archives/GZip/GZipArchive.cs) by adding XML documentation explaining single-entry limitation and relationship to GZip compression used in Tar.gz
-
-## Further Considerations
-
-1. **Breaking changes roadmap** - Should we plan a major version (2.0) to remove deprecated factory methods, clean up `ArchiveType` enum (remove Arc/Arj or add full support), and consolidate naming patterns?
-
-2. **Progress reporting consistency** - Should `IProgress<ArchiveExtractionProgress<IEntry>>` be added to all extraction extension methods or consolidated into options classes?
-
-## Detailed Analysis
-
-### Factory Pattern Issues
-
-Three different factory patterns exist with overlapping functionality:
-
-1. **Static Factories**: ArchiveFactory, ReaderFactory, WriterFactory
-2. **Instance Factories**: IArchiveFactory, IReaderFactory, IWriterFactory
-3. **Format-specific static methods**: Each archive class has static `Open` methods
-
-**Example confusion:**
-```csharp
-// Three ways to open a Zip archive - which is recommended?
-var archive1 = ArchiveFactory.Open("file.zip");
-var archive2 = ZipArchive.Open("file.zip");
-var archive3 = ArchiveFactory.AutoFactory.Open(fileInfo, options);
-```
-
-### Async Support Gaps
-
-Base `IWriter` interface has async methods, but writer implementations provide minimal async support. Most writers just call synchronous methods:
-
-```csharp
-public virtual async Task WriteAsync(...)
-{
-    // Default implementation calls synchronous version
-    Write(filename, source, modificationTime);
-    await Task.CompletedTask.ConfigureAwait(false);
-}
-```
-
-Real async implementations only in:
-- `TarWriter` - Proper async implementation
-- Most other writers use sync-over-async
-
-### GZip Archive Special Case
-
-GZip is treated as both a compression format and an archive format, but only supports single-entry archives:
-
-```csharp
-protected override GZipArchiveEntry CreateEntryInternal(...)
-{
-    if (Entries.Any())
-    {
-        throw new InvalidFormatException("Only one entry is allowed in a GZip Archive");
-    }
-    // ...
-}
-```
-
-### Options Class Hierarchy
-
-```
-OptionsBase (LeaveStreamOpen, ArchiveEncoding)
-  ├─ ReaderOptions (LookForHeader, Password, DisableCheckIncomplete, BufferSize, ExtensionHint, Progress)
-  ├─ WriterOptions (CompressionType, CompressionLevel, Progress)
-  │   ├─ ZipWriterOptions (ArchiveComment, UseZip64)
-  │   ├─ TarWriterOptions (FinalizeArchiveOnClose, HeaderFormat)
-  │   └─ GZipWriterOptions (no additional properties)
-  └─ ExtractionOptions (standalone - Overwrite, ExtractFullPath, PreserveFileTime, PreserveAttributes)
-```
-
-**Issues:**
-- `ExtractionOptions` doesn't inherit from `OptionsBase` - no encoding support during extraction
-- Progress reporting inconsistency between readers and extraction
-- Obsolete properties (`ChecksumIsValid`, `Version`) with unclear migration path
-
-### Implementation Priorities
-
-**High Priority (Non-Breaking):**
-1. Add API usage guide (Archive vs Reader, factory recommendations, async best practices)
-2. Fix progress reporting consistency
-3. Complete async implementation in writers
-
-**Medium Priority (Next Major Version):**
-1. Unify factory pattern - deprecate format-specific static `Open` methods
-2. Clean up options classes - make `ExtractionOptions` inherit from `OptionsBase`
-3. Clarify archive types - remove Arc/Arj from `ArchiveType` enum or add full support
-4. Standardize naming across archive types
-
-**Low Priority:**
-1. Add BZip2 archive support similar to GZipArchive
-2. Complete obsolete property cleanup with migration guide
-
-### Backward Compatibility Strategy
-
-**Safe (Non-Breaking) Changes:**
-- Add new methods to interfaces (use default implementations)
-- Add new options properties (with defaults)
-- Add new factory methods
-- Improve async implementations
-- Add progress reporting support
-
-**Breaking Changes to Avoid:**
-- ❌ Removing format-specific `Open` methods (deprecate instead)
-- ❌ Changing `LeaveStreamOpen` default (currently `true`)
-- ❌ Removing obsolete properties before major version bump
-- ❌ Changing return types or signatures of existing methods
-
-**Deprecation Pattern:**
-- Use `[Obsolete]` for one major version
-- Use `[EditorBrowsable(EditorBrowsableState.Never)]` in next major version
-- Remove in following major version

-# NuGet Release Workflow
-
-This document describes the automated NuGet release workflow for SharpCompress.
-
-## Overview
-
-The `nuget-release.yml` workflow automatically builds, tests, and publishes SharpCompress packages to NuGet.org when:
-- Changes are pushed to the `master` or `release` branch
-- A version tag (format: `MAJOR.MINOR.PATCH`) is pushed
-
-The workflow runs on both Windows and Ubuntu, but only the Windows build publishes to NuGet.
-
-## How It Works
-
-### Version Determination
-
-The workflow automatically determines the version based on whether the commit is tagged using C# code in the build project:
-
-1. **Tagged Release (Stable)**:
-   - If the current commit has a version tag (e.g., `0.42.1`)
-   - Uses the tag as the version number
-   - Published as a stable release
-
-2. **Untagged Release (Prerelease)**:
-   - If the current commit is NOT tagged
-   - Creates a prerelease version based on the next minor version
-   - Format: `{NEXT_MINOR_VERSION}-beta.{COMMIT_COUNT}`
-   - Example: `0.43.0-beta.123` (if last tag is 0.42.x)
-   - Published as a prerelease to NuGet.org (Windows build only)
-
-### Workflow Steps
-
-The workflow runs on a matrix of operating systems (Windows and Ubuntu):
-
-1. **Checkout**: Fetches the repository with full history for version detection
-2. **Setup .NET**: Installs .NET 10.0
-3. **Determine Version**: Runs `determine-version` build target to check for tags and determine version
-4. **Update Version**: Runs `update-version` build target to update the version in the project file
-5. **Build and Test**: Runs the full build and test suite on both platforms
-6. **Upload Artifacts**: Uploads the generated `.nupkg` files as workflow artifacts (separate for each OS)
-7. **Push to NuGet**: (Windows only) Runs `push-to-nuget` build target to publish the package to NuGet.org using the API key
-
-All version detection, file updates, and publishing logic is implemented in C# in the `build/Program.cs` file using build targets.
-
-## Setup Requirements
-
-### 1. NuGet API Key Secret
-
-The workflow requires a `NUGET_API_KEY` secret to be configured in the repository settings:
-
-1. Go to https://www.nuget.org/account/apikeys
-2. Create a new API key with "Push" permission for the SharpCompress package
-3. In GitHub, go to: **Settings** → **Secrets and variables** → **Actions**
-4. Create a new secret named `NUGET_API_KEY` with the API key value
-
-### 2. Branch Protection (Recommended)
-
-Consider enabling branch protection rules for the `release` branch to ensure:
-- Code reviews are required before merging
-- Status checks pass before merging
-- Only authorized users can push to the branch
-
-## Usage
-
-### Creating a Stable Release
-
-There are two ways to trigger a stable release:
-
-**Method 1: Push tag to trigger workflow**
-1. Ensure all changes are committed on the `master` or `release` branch
-2. Create and push a version tag:
-   ```bash
-   git checkout master  # or release
-   git tag 0.43.0
-   git push origin 0.43.0
-   ```
-3. The workflow will automatically trigger, build, test, and publish `SharpCompress 0.43.0` to NuGet.org (Windows build)
-
-**Method 2: Tag after pushing to branch**
-1. Ensure all changes are merged and pushed to the `master` or `release` branch
-2. Create and push a version tag on the already-pushed commit:
-   ```bash
-   git checkout master  # or release
-   git tag 0.43.0
-   git push origin 0.43.0
-   ```
-3. The workflow will automatically trigger, build, test, and publish `SharpCompress 0.43.0` to NuGet.org (Windows build)
-
-### Creating a Prerelease
-
-1. Push changes to the `master` or `release` branch without tagging:
-   ```bash
-   git checkout master  # or release
-   git push origin master  # or release
-   ```
-2. The workflow will automatically:
-   - Build and test the project on both Windows and Ubuntu
-   - Publish a prerelease version like `0.43.0-beta.456` to NuGet.org (Windows build)
-
-## Troubleshooting
-
-### Workflow Fails to Push to NuGet
-
-- **Check the API Key**: Ensure `NUGET_API_KEY` is set correctly in repository secrets
-- **Check API Key Permissions**: Verify the API key has "Push" permission for SharpCompress
-- **Check API Key Expiration**: NuGet API keys may expire; create a new one if needed
-
-### Version Conflict
-
-If you see "Package already exists" errors:
-- The workflow uses `--skip-duplicate` flag to handle this gracefully
-- If you need to republish the same version, delete it from NuGet.org first (if allowed)
-
-### Build or Test Failures
-
-- The workflow will not push to NuGet if build or tests fail
-- Check the workflow logs in GitHub Actions for details
-- Fix the issues and push again
-
-## Manual Package Creation
-
-If you need to create a package manually without publishing:
-
-```bash
-dotnet run --project build/build.csproj -- publish
-```
-
-The package will be created in the `artifacts/` directory.
-
-## Build Targets
-
-The workflow uses the following C# build targets defined in `build/Program.cs`:
-
-- **determine-version**: Detects version from git tags and outputs VERSION and PRERELEASE variables
-- **update-version**: Updates VersionPrefix, AssemblyVersion, and FileVersion in the project file
-- **push-to-nuget**: Pushes the generated NuGet packages to NuGet.org (requires NUGET_API_KEY)
-
-These targets can be run manually for testing:
-
-```bash
-# Determine the version
-dotnet run --project build/build.csproj -- determine-version
-
-# Update version in project file
-VERSION=0.43.0 dotnet run --project build/build.csproj -- update-version
-
-# Push to NuGet (requires NUGET_API_KEY environment variable)
-NUGET_API_KEY=your-key dotnet run --project build/build.csproj -- push-to-nuget
-```

-# Testing Guide for NuGet Release Workflow
-
-This document describes how to test the NuGet release workflow.
-
-## Testing Strategy
-
-Since this workflow publishes to NuGet.org and requires repository secrets, testing should be done carefully. The workflow runs on both Windows and Ubuntu, but only the Windows build publishes to NuGet.
-
-## Pre-Testing Checklist
-
-- [x] Workflow YAML syntax validated
-- [x] Version determination logic tested locally
-- [x] Version update logic tested locally
-- [x] Build script works (`dotnet run --project build/build.csproj`)
-
-## Manual Testing Steps
-
-### 1. Test Prerelease Publishing (Recommended First Test)
-
-This tests the workflow on untagged commits to the master or release branch.
-
-**Steps:**
-1. Ensure `NUGET_API_KEY` secret is configured in repository settings
-2. Create a test commit on the `master` or `release` branch (e.g., update a comment or README)
-3. Push to the `master` or `release` branch
-4. Monitor the GitHub Actions workflow at: https://github.com/adamhathcock/sharpcompress/actions
-5. Verify:
-   - Workflow triggers and runs successfully on both Windows and Ubuntu
-   - Version is determined correctly (e.g., `0.43.0-beta.XXX` if last tag is 0.42.x)
-   - Build and tests pass on both platforms
-   - Package artifacts are uploaded for both platforms
-   - Package is pushed to NuGet.org as prerelease (Windows build only)
-
-**Expected Outcome:**
-- A new prerelease package appears on NuGet.org: https://www.nuget.org/packages/SharpCompress/
-- Package version follows pattern: `{NEXT_MINOR_VERSION}-beta.{COMMIT_COUNT}`
-
-### 2. Test Tagged Release Publishing
-
-This tests the workflow when a version tag is pushed.
-
-**Steps:**
-1. Prepare the `master` or `release` branch with all desired changes
-2. Create a version tag (must be a pure semantic version like `MAJOR.MINOR.PATCH`):
-   ```bash
-   git checkout master  # or release
-   git tag 0.42.2
-   git push origin 0.42.2
-   ```
-3. Monitor the GitHub Actions workflow
-4. Verify:
-   - Workflow triggers and runs successfully on both Windows and Ubuntu
-   - Version is determined as the tag (e.g., `0.42.2`)
-   - Build and tests pass on both platforms
-   - Package artifacts are uploaded for both platforms
-   - Package is pushed to NuGet.org as stable release (Windows build only)
-
-**Expected Outcome:**
-- A new stable release package appears on NuGet.org
-- Package version matches the tag
-
-### 3. Test Duplicate Package Handling
-
-This tests the `--skip-duplicate` flag behavior.
-
-**Steps:**
-1. Push to the `release` branch without making changes
-2. Monitor the workflow
-3. Verify:
-   - Workflow runs but NuGet push is skipped with "duplicate" message
-   - No errors occur
-
-### 4. Test Build Failure Handling
-
-This tests that failed builds don't publish packages.
-
-**Steps:**
-1. Introduce a breaking change in a test or code
-2. Push to the `release` branch
-3. Verify:
-   - Workflow runs and detects the failure
-   - Build or test step fails
-   - NuGet push step is skipped
-   - No package is published
-
-## Verification
-
-After each test, verify:
-
-1. **GitHub Actions Logs**: Check the workflow logs for any errors or warnings
-2. **NuGet.org**: Verify the package appears with correct version and metadata
-3. **Artifacts**: Download and inspect the uploaded artifacts
-
-## Rollback/Cleanup
-
-If testing produces unwanted packages:
-
-1. **Prerelease packages**: Can be unlisted on NuGet.org (Settings → Unlist)
-2. **Stable packages**: Cannot be deleted, only unlisted (use test versions)
-3. **Tags**: Can be deleted with:

-## Known Limitations
-
-- NuGet.org does not allow re-uploading the same version
-- Deleted packages on NuGet.org reserve the version number
-- The workflow requires the `NUGET_API_KEY` secret to be set
-
-## Success Criteria
-
-The workflow is considered successful if:
-
-- ✅ Prerelease versions are published correctly with beta suffix
-- ✅ Tagged versions are published as stable releases
-- ✅ Build and test failures prevent publishing
-- ✅ Duplicate packages are handled gracefully
-- ✅ Workflow logs are clear and informative

-description: 'Guidelines for building SharpCompress - A C# compression library'
-applyTo: '**/*.cs'
----
-
-# SharpCompress Development
-
-## About SharpCompress
-SharpCompress is a pure C# compression library supporting multiple archive formats (Zip, Tar, GZip, BZip2, 7Zip, Rar, LZip, XZ, ZStandard) for .NET Framework 4.62, .NET Standard 2.1, .NET 6.0, and .NET 8.0. The library provides both seekable Archive APIs and forward-only Reader/Writer APIs for streaming scenarios.
-
-## C# Instructions
-- Always use the latest version C#, currently C# 13 features.
-- Write clear and concise comments for each function.
-- Follow the existing code style and patterns in the codebase.
-
-## General Instructions
-- **Agents should NEVER commit to git** - Agents should stage files and leave committing to the user. Only create commits when the user explicitly requests them.
-- Make only high confidence suggestions when reviewing code changes.
-- Write code with good maintainability practices, including comments on why certain design decisions were made.
-- Handle edge cases and write clear exception handling.
-- For libraries or external dependencies, mention their usage and purpose in comments.
-- Preserve backward compatibility when making changes to public APIs.
-
-## Naming Conventions
-
-- Follow PascalCase for component names, method names, and public members.
-- Use camelCase for private fields and local variables.
-- Prefix interface names with "I" (e.g., IUserService).
-
-## Code Formatting
-
-**Copilot agents: You MUST run the `format` task after making code changes to ensure consistency.**
-
-- Use CSharpier for code formatting to ensure consistent style across the project
-- CSharpier is configured as a local tool in `.config/dotnet-tools.json`
-
-### Commands
-
-1. **Restore tools** (first time only):
-   ```bash
-   dotnet tool restore
-   ```
-
-2. **Check if files are formatted correctly** (doesn't modify files):
-   ```bash
-   dotnet csharpier check .
-   ```
-   - Exit code 0: All files are properly formatted
-   - Exit code 1: Some files need formatting (will show which files and differences)
-
-3. **Format files** (modifies files):
-   ```bash
-   dotnet csharpier format .
-   ```
-   - Formats all files in the project to match CSharpier style
-   - Run from project root directory
-
-4. **Configure your IDE** to format on save using CSharpier for the best experience
-
-### Additional Notes
-- The project also uses `.editorconfig` for editor settings (indentation, encoding, etc.)
-- Let CSharpier handle code style while `.editorconfig` handles editor behavior
-- Always run `dotnet csharpier check .` before committing to verify formatting
-
-## Project Setup and Structure
-
-- The project targets multiple frameworks: .NET Framework 4.62, .NET Standard 2.1, .NET 6.0, and .NET 8.0
-- Main library is in `src/SharpCompress/`
-- Tests are in `tests/SharpCompress.Test/`
-- Performance tests are in `tests/SharpCompress.Performance/`
-- Test archives are in `tests/TestArchives/`
-- Build project is in `build/`
-- Use `dotnet build` to build the solution
-- Use `dotnet test` to run tests
-- Solution file: `SharpCompress.sln`

-  ├── TestBase.cs      # Base test class with helper methods
-  └── TestArchives/    # Test data (not checked into main test project)
-```
-
-### Factory Pattern
-All format types implement factory interfaces (`IArchiveFactory`, `IReaderFactory`, `IWriterFactory`) for auto-detection:
-- `ReaderFactory.Open()` - Auto-detects format by probing stream
-- `WriterFactory.Open()` - Creates writer for specified `ArchiveType`
-- Factories located in: `src/SharpCompress/Factories/`
-
-## Nullable Reference Types
-
-- Declare variables non-nullable, and check for `null` at entry points.
-- Always use `is null` or `is not null` instead of `== null` or `!= null`.
-- Trust the C# null annotations and don't add null checks when the type system says a value cannot be null.
-
-## SharpCompress-Specific Guidelines
-
-### Supported Formats
-SharpCompress supports multiple archive and compression formats:
-- **Archive Formats**: Zip, Tar, 7Zip, Rar (read-only)
-- **Compression**: DEFLATE, BZip2, LZMA/LZMA2, PPMd, ZStandard (decompress only), Deflate64 (decompress only)
-- **Combined Formats**: Tar.GZip, Tar.BZip2, Tar.LZip, Tar.XZ, Tar.ZStandard
-- See [docs/FORMATS.md](docs/FORMATS.md) for complete format support matrix
-
-### Stream Handling Rules
-- **Disposal**: As of version 0.21, SharpCompress closes wrapped streams by default
-- Use `ReaderOptions` or `WriterOptions` with `LeaveStreamOpen = true` to control stream disposal
-- Use `NonDisposingStream` wrapper when working with compression streams directly to prevent disposal
-- Always dispose of readers, writers, and archives in `using` blocks
-- For forward-only operations, use Reader/Writer APIs; for random access, use Archive APIs
-
-### Async/Await Patterns
-- All I/O operations support async/await with `CancellationToken`
-- Async methods follow the naming convention: `MethodNameAsync`
-- Key async methods:
-  - `WriteEntryToAsync` - Extract entry asynchronously
-  - `WriteAllToDirectoryAsync` - Extract all entries asynchronously
-  - `WriteAsync` - Write entry asynchronously
-  - `WriteAllAsync` - Write directory asynchronously
-  - `OpenEntryStreamAsync` - Open entry stream asynchronously
-- Always provide `CancellationToken` parameter in async methods
-
-### Archive APIs vs Reader/Writer APIs
-- **Archive API**: Use for random access with seekable streams (e.g., `ZipArchive`, `TarArchive`)
-- **Reader API**: Use for forward-only reading on non-seekable streams (e.g., `ZipReader`, `TarReader`)
-- **Writer API**: Use for forward-only writing on streams (e.g., `ZipWriter`, `TarWriter`)
-- 7Zip only supports Archive API due to format limitations
-
-### Tar-Specific Considerations
-- Tar format requires file size in the header
-- If no size is specified to TarWriter and the stream is not seekable, an exception will be thrown
-- Tar combined with compression (GZip, BZip2, LZip, XZ) is supported
-
-### Zip-Specific Considerations
-- Supports Zip64 for large files (seekable streams only)
-- Supports PKWare and WinZip AES encryption
-- Multiple compression methods: None, Shrink, Reduce, Implode, DEFLATE, Deflate64, BZip2, LZMA, PPMd
-- Encrypted LZMA is not supported
-
-### Performance Considerations
-- For large files, use Reader/Writer APIs with non-seekable streams to avoid loading entire file in memory
-- Leverage async I/O for better scalability
-- Consider compression level trade-offs (speed vs. size)
-- Use appropriate buffer sizes for stream operations
-
-## Testing
-
-- Always include test cases for critical paths of the application.
-- Test with multiple archive formats when making changes to core functionality.
-- Include tests for both Archive and Reader/Writer APIs when applicable.
-- Test async operations with cancellation tokens.
-- Do not emit "Act", "Arrange" or "Assert" comments.
-- Copy existing style in nearby files for test method names and capitalization.
-- Use test archives from `tests/TestArchives` directory for consistency.
-- Test stream disposal and `LeaveStreamOpen` behavior.
-- Test edge cases: empty archives, large files, corrupted archives, encrypted archives.
-
-### Test Organization
-- Base class: `TestBase` - Provides `TEST_ARCHIVES_PATH`, `SCRATCH_FILES_PATH`, temp directory management
-- Framework: xUnit with AwesomeAssertions
-- Test archives: `tests/TestArchives/` - Use existing archives, don't create new ones unnecessarily
-- Match naming style of nearby test files
-
-## Common Pitfalls
-
-1. **Don't mix Archive and Reader APIs** - Archive needs seekable stream, Reader doesn't
-2. **Solid archives (Rar, 7Zip)** - Use `ExtractAllEntries()` for best performance, not individual entry extraction
-3. **Stream disposal** - Always set `LeaveStreamOpen` explicitly when needed (default is to close)
-4. **Tar + non-seekable stream** - Must provide file size or it will throw
-5. **Multi-framework differences** - Some features differ between .NET Framework and modern .NET (e.g., Mono.Posix)
-6. **Format detection** - Use `ReaderFactory.Open()` for auto-detection, test with actual archive files

+# Formats
+
+## Accessing Archives
+
+- Archive classes allow random access to a seekable stream.
+- Reader classes allow forward-only reading on a stream.
+- Writer classes allow forward-only Writing on a stream.
+
+## Supported Format Table
+
+| Archive Format | Compression Format(s) | Compress/Decompress | Archive API | Reader API | Writer API |
+| --- | --- | --- | --- | --- | --- |
+| Rar | Rar | Decompress (1) | RarArchive | RarReader | N/A |
+| Zip (2) | None, DEFLATE, BZip2, LZMA/LZMA2, PPMd | Both | ZipArchive | ZipReader | ZipWriter |
+| Tar | None | Both | TarArchive | TarReader | TarWriter (3)  |
+| Tar.GZip | DEFLATE | Both | TarArchive | TarReader | TarWriter (3)  |
+| Tar.BZip2 | BZip2 | Both | TarArchive | TarReader | TarWriter (3)  |
+| Tar.LZip | LZMA | Both | TarArchive | TarReader | TarWriter (3)  |
+| Tar.XZ | LZMA2 | Decompress | TarArchive | TarReader | TarWriter (3)  |
+| GZip (single file) | DEFLATE | Both | GZipArchive | GZipReader | GZipWriter |
+| 7Zip (4) | LZMA, LZMA2, BZip2, PPMd, BCJ, BCJ2, Deflate | Decompress | SevenZipArchive | N/A | N/A |
+| LZip (single file) (5) | LZip (LZMA) | Both | LZipArchive | LZipReader | LZipWriter |
+
+ 1. SOLID Rars are only supported in the RarReader API.
+ 2. Zip format supports pkware and WinzipAES encryption.  However, encrypted LZMA is not supported.  Zip64 reading/writing is supported but only with seekable streams as the Zip spec doesn't support Zip64 data in post data descriptors.
+ 3. The Tar format requires a file size in the header.  If no size is specified to the TarWriter and the stream is not seekable, then an exception will be thrown.
+ 4. The 7Zip format doesn't allow for reading as a forward-only stream so 7Zip is only supported through the Archive API
+ 5. LZip has no support for extra data like the file name or timestamp.  There is a default filename used when looking at the entry Key on the archive.
+
+## Compression Streams
+
+For those who want to directly compress/decompress bits.  The single file formats are represented here as well.  However, BZip2, LZip and XZ have no metadata (GZip has a little) so using them without something like a Tar file makes little sense.
+
+| Compressor | Compress/Decompress |
+| --- | --- |
+| BZip2Stream | Both |
+| GZipStream | Both |
+| DeflateStream | Both |
+| LZMAStream | Both |
+| PPMdStream | Both |
+| ADCStream | Decompress |
+| LZipStream | Both |
+| XZStream | Decompress |
+
+## Archive Formats vs Compression 
+
+Sometimes the terminology gets mixed.
+
+### Compression
+
+DEFLATE, LZMA are pure compression algorithms
+
+### Formats
+
+Formats like Zip, 7Zip, Rar are archive formats only.  They use other compression methods (e.g. DEFLATE, LZMA, etc.) or propriatory (e.g RAR)
+
+### Overlap
+
+GZip, BZip2 and LZip are single file archival formats.  The overlap in the API happens because Tar uses the single file formats as "compression" methods and the API tries to hide this a bit.

 ## Recommended Formats
 
-In general, I recommend GZip (Deflate)/BZip2 (BZip)/LZip (LZMA) as the simplicity of the formats lend to better long term archival as well as the streamability. Tar is often used in conjunction for multiple files in a single archive (e.g. `.tar.gz`)

-Zip is okay, but it's a very hap-hazard format and the variation in headers and implementations makes it hard to get correct. Uses Deflate by default but supports a lot of compression methods.

-7Zip and XZ both are overly complicated. 7Zip does not support streamable formats. XZ has known holes explained here: (http://www.nongnu.org/lzip/xz_inadequate.html) Use Tar/LZip for LZMA compression instead.

-ZStandard is an efficient format that works well for streaming with a flexible compression level to tweak the speed/performance trade off you are looking for.  We currently only implement decompression for ZStandard but as we leverage the [ZstdSharp](https://github.com/oleg-st/ZstdSharp) library one could likely add compression support without much trouble (PRs are welcome!).

+# SharpCompress Usage
+
+## Stream Rules
+When dealing with Streams, the rule should be that you don't close a stream you didn't create.  This, in effect, should mean you should always put a Stream in a using block to dispose it.
+
+However, the .NET Framework often has classes that will dispose streams by default to make things "easy" like the following:
+
+```C#
+using (var reader = new StreamReader(File.Open("foo")))
+{
+    ...
+}
+```
+
+In this example, reader should get disposed.  However, stream rules should say the the `FileStream` created by `File.Open` should remain open.  However, the .NET Framework closes it for you by default unless you override the constructor.  In general, you should be writing Stream code like this:
+
+```C#
+using (var fileStream = File.Open("foo"))
+using (var reader = new StreamReader(fileStream))
+{
+    ...
+}
+```
+
+To deal with the "correct" rules as well as the expectations of users, I've decided on this:
+
+* When writing, leave streams open.
+* When reading, close streams 
+
+To be explicit though, consider always using the overloads that use `ReaderOptions` or `WriterOptions` and explicitly set `LeaveStreamOpen` the way you want.
+
+## Samples
+
+Also, look over the tests for more thorough [examples](https://github.com/adamhathcock/sharpcompress/tree/master/test/SharpCompress.Test)
+
+### Create Zip Archive from all files in a directory to a file
+
+```C#
+using (var archive = ZipArchive.Create())
+{
+    archive.AddAllFromDirectory("D:\\temp");
+    archive.SaveTo("C:\\temp.zip", CompressionType.Deflate);
+}
+```
+
+
+### Create Zip Archive from all files in a directory and save in memory
+
+```C#
+
+var memoryStream = new MemoryStream();
+using (var archive = ZipArchive.Create())
+{
+    archive.AddAllFromDirectory("D:\\temp");
+    archive.SaveTo(memoryStream, new WriterOptions(CompressionType.Deflate)
+                                {
+                                    LeaveStreamOpen = true
+                                });
+}
+//reset memoryStream to be usable now
+memoryStream.Position = 0;
+```
+
+### Extract all files from a Rar file to a directory using RarArchive
+
+```C#
+using (var archive = RarArchive.Open("Test.rar"))
+{
+    foreach (var entry in archive.Entries.Where(entry => !entry.IsDirectory))
+    {
+        entry.WriteToDirectory("D:\\temp", new ExtractionOptions()
+        {
+            ExtractFullPath = true,
+            Overwrite = true
+        });
+    }
+}
+```
+
+### Use ReaderFactory to autodetect archive type and Open the entry stream
+
+```C#
+using (Stream stream = File.OpenRead("Tar.tar.bz2"))
+using (var reader = ReaderFactory.Open(stream))
+{
+    while (reader.MoveToNextEntry())
+    {
+        if (!reader.Entry.IsDirectory)
+        {
+            Console.WriteLine(reader.Entry.Key);
+            reader.WriteEntryToDirectory(@"C:\temp", new ExtractionOptions()
+            {
+                ExtractFullPath = true,
+                Overwrite = true
+            });
+        }
+    }
+}
+```
+
+### Use ReaderFactory to autodetect archive type and Open the entry stream
+
+```C#
+using (Stream stream = File.OpenRead("Tar.tar.bz2"))
+using (var reader = ReaderFactory.Open(stream))
+{
+    while (reader.MoveToNextEntry())
+    {
+        if (!reader.Entry.IsDirectory)
+        {
+            using (var entryStream = reader.OpenEntryStream())
+            {
+                entryStream.CopyTo(...);
+            }
+        }
+    }
+}
+```
+
+### Use WriterFactory to write all files from a directory in a streaming manner.
+
+```C#
+using (Stream stream = File.OpenWrite("C:\\temp.tgz"))
+using (var writer = WriterFactory.Open(stream, ArchiveType.Tar, new WriterOptions(CompressionType.GZip)
+                                                {
+                                                    LeaveOpenStream = true
+                                                }))
+{
+    writer.WriteAll("D:\\temp", "*", SearchOption.AllDirectories);
+}
+```

-};
-archive.SaveTo("output.zip", options);
-```
-
-### ExtractionOptions

-    PreserveFileTime = true                         // Keep original timestamps
-};
-archive.WriteToDirectory(@"C:\output", options);
-```
-
----
-
-## Compression Types
-
-### Available Compressions
-
-```csharp
-// For creating archives
-CompressionType.None       // No compression (store)
-CompressionType.Deflate    // DEFLATE (default for ZIP/GZip)
-CompressionType.BZip2      // BZip2
-CompressionType.LZMA       // LZMA (for 7Zip, LZip, XZ)
-CompressionType.PPMd       // PPMd (for ZIP)
-CompressionType.Rar        // RAR compression (read-only)
-
-// For Tar archives
-// Use CompressionType in TarWriter constructor
-using (var writer = TarWriter(stream, CompressionType.GZip))  // Tar.GZip
-using (var writer = TarWriter(stream, CompressionType.BZip2)) // Tar.BZip2
-```
-
-### Archive Types
-
-```csharp
-ArchiveType.Zip
-ArchiveType.Tar
-ArchiveType.GZip
-ArchiveType.BZip2
-ArchiveType.Rar
-ArchiveType.SevenZip

-ArchiveType.ZStandard
-```
-
----
-
-## Patterns & Examples
-
-### Extract with Error Handling
-
-```csharp
-try
-{
-    using (var archive = ZipArchive.Open("archive.zip", 
-        new ReaderOptions { Password = "password" }))
-    {
-        archive.WriteToDirectory(@"C:\output", new ExtractionOptions
-        {
-            ExtractFullPath = true,
-            Overwrite = true
-        });
-    }
-}
-catch (PasswordRequiredException)
-{
-    Console.WriteLine("Password required");
-}
-catch (InvalidArchiveException)
-{
-    Console.WriteLine("Archive is invalid");
-}
-catch (SharpCompressException ex)
-{
-    Console.WriteLine($"Error: {ex.Message}");
-}
-```
-
-### Extract with Progress
-
-```csharp
-var progress = new Progress<ProgressReport>(report =>
-{
-    Console.WriteLine($"Extracting {report.EntryPath}: {report.PercentComplete}%");
-});
-
-var options = new ReaderOptions { Progress = progress };
-using (var archive = ZipArchive.Open("archive.zip", options))
-{
-    archive.WriteToDirectory(@"C:\output");
-}
-```
-
-### Async Extract with Cancellation
-
-```csharp
-var cts = new CancellationTokenSource();
-cts.CancelAfter(TimeSpan.FromMinutes(5));
-
-try
-{
-    using (var archive = ZipArchive.Open("archive.zip"))
-    {
-        await archive.WriteToDirectoryAsync(@"C:\output",
-            new ExtractionOptions { ExtractFullPath = true, Overwrite = true },
-            cts.Token);
-    }
-}
-catch (OperationCanceledException)
-{
-    Console.WriteLine("Extraction cancelled");
-}
-```
-
-### Create with Custom Compression
-
-```csharp
-using (var archive = ZipArchive.Create())
-{
-    archive.AddAllFromDirectory(@"D:\source");
-    
-    // Fastest
-    archive.SaveTo("fast.zip", new WriterOptions(CompressionType.Deflate) 
-    { 
-        CompressionLevel = 1 
-    });
-    
-    // Balanced (default)
-    archive.SaveTo("normal.zip", CompressionType.Deflate);
-    
-    // Best compression
-    archive.SaveTo("best.zip", new WriterOptions(CompressionType.Deflate) 
-    { 
-        CompressionLevel = 9 
-    });
-}
-```
-
-### Stream Processing (No File I/O)
-
-```csharp
-using (var outputStream = new MemoryStream())
-using (var archive = ZipArchive.Create())
-{
-    // Add content from memory
-    using (var contentStream = new MemoryStream(Encoding.UTF8.GetBytes("Hello")))
-    {
-        archive.AddEntry("file.txt", contentStream);
-    }
-    
-    // Save to memory
-    archive.SaveTo(outputStream, CompressionType.Deflate);
-    
-    // Get bytes
-    byte[] archiveBytes = outputStream.ToArray();
-}
-```
-
-### Extract Specific Files
-
-```csharp
-using (var archive = ZipArchive.Open("archive.zip"))
-{
-    var filesToExtract = new[] { "file1.txt", "file2.txt" };
-    
-    foreach (var entry in archive.Entries.Where(e => filesToExtract.Contains(e.Key)))
-    {
-        entry.WriteToFile(@"C:\output\" + entry.Key);
-    }
-}
-```
-
-### List Archive Contents
-
-```csharp
-using (var archive = ZipArchive.Open("archive.zip"))
-{
-    foreach (var entry in archive.Entries)
-    {
-        if (entry.IsDirectory)
-            Console.WriteLine($"[DIR]  {entry.Key}");
-        else
-            Console.WriteLine($"[FILE] {entry.Key} ({entry.Size} bytes)");
-    }
-}
-```
-
----
-
-## Common Mistakes
-
-### ✗ Wrong - Stream not disposed
-
-```csharp
-var stream = File.OpenRead("archive.zip");
-var archive = ZipArchive.Open(stream);
-archive.WriteToDirectory(@"C:\output");
-// stream not disposed - leaked resource
-```
-
-### ✓ Correct - Using blocks
-
-```csharp
-using (var stream = File.OpenRead("archive.zip"))
-using (var archive = ZipArchive.Open(stream))
-{
-    archive.WriteToDirectory(@"C:\output");
-}
-// Both properly disposed
-```
-
-### ✗ Wrong - Mixing API styles
-
-```csharp
-// Loading entire archive then iterating
-using (var archive = ZipArchive.Open("large.zip"))
-{
-    var entries = archive.Entries.ToList();  // Loads all in memory
-    foreach (var e in entries)
-    {
-        e.WriteToFile(...);  // Then extracts each
-    }
-}
-```
-
-### ✓ Correct - Use Reader for large files
-
-```csharp
-// Streaming iteration
-using (var stream = File.OpenRead("large.zip"))
-using (var reader = ReaderFactory.Open(stream))
-{
-    while (reader.MoveToNextEntry())
-    {
-        reader.WriteEntryToDirectory(@"C:\output");
-    }
-}
-```

-# SharpCompress Architecture Guide
-
-This guide explains the internal architecture and design patterns of SharpCompress for contributors.
-
-## Overview
-
-SharpCompress is organized into three main layers:
-
-```
-┌─────────────────────────────────────────┐
-│     User-Facing APIs (Top Layer)        │
-│  Archive, Reader, Writer Factories      │
-├─────────────────────────────────────────┤
-│     Format-Specific Implementations     │
-│  ZipArchive, TarReader, GZipWriter,     │
-│  RarArchive, SevenZipArchive, etc.      │
-├─────────────────────────────────────────┤
-│     Compression & Crypto (Bottom Layer) │
-│  Deflate, LZMA, BZip2, AES, CRC32       │
-└─────────────────────────────────────────┘
-```
-
----
-
-## Directory Structure
-
-### `src/SharpCompress/`
-
-#### `Archives/` - Archive Implementations
-Contains `IArchive` implementations for seekable, random-access APIs.
-
-**Key Files:**
-- `AbstractArchive.cs` - Base class for all archives
-- `IArchive.cs` - Archive interface definition
-- `ArchiveFactory.cs` - Factory for opening archives
-- Format-specific: `ZipArchive.cs`, `TarArchive.cs`, `RarArchive.cs`, `SevenZipArchive.cs`, `GZipArchive.cs`
-
-**Use Archive API when:**
-- Stream is seekable (file, memory)
-- Need random access to entries
-- Archive fits in memory
-- Simplicity is important
-
-#### `Readers/` - Reader Implementations
-Contains `IReader` implementations for forward-only, non-seekable APIs.
-
-**Key Files:**
-- `AbstractReader.cs` - Base reader class
-- `IReader.cs` - Reader interface
-- `ReaderFactory.cs` - Auto-detection factory
-- `ReaderOptions.cs` - Configuration for readers
-- Format-specific: `ZipReader.cs`, `TarReader.cs`, `GZipReader.cs`, `RarReader.cs`, etc.
-
-**Use Reader API when:**
-- Stream is non-seekable (network, pipe, compressed)
-- Processing large files
-- Memory is limited
-- Forward-only processing is acceptable
-
-#### `Writers/` - Writer Implementations
-Contains `IWriter` implementations for forward-only writing.
-
-**Key Files:**
-- `AbstractWriter.cs` - Base writer class
-- `IWriter.cs` - Writer interface
-- `WriterFactory.cs` - Factory for creating writers
-- `WriterOptions.cs` - Configuration for writers
-- Format-specific: `ZipWriter.cs`, `TarWriter.cs`, `GZipWriter.cs`
-
-#### `Factories/` - Format Detection
-Factory classes for auto-detecting archive format and creating appropriate readers/writers.
-
-**Key Files:**
-- `Factory.cs` - Base factory class
-- `IFactory.cs` - Factory interface
-- Format-specific: `ZipFactory.cs`, `TarFactory.cs`, `RarFactory.cs`, etc.
-
-**How It Works:**
-1. `ReaderFactory.Open(stream)` probes stream signatures
-2. Identifies format by magic bytes
-3. Creates appropriate reader instance
-4. Returns generic `IReader` interface
-
-#### `Common/` - Shared Types
-Common types, options, and enumerations used across formats.
-
-**Key Files:**
-- `IEntry.cs` - Entry interface (file within archive)
-- `Entry.cs` - Entry implementation
-- `ArchiveType.cs` - Enum for archive formats
-- `CompressionType.cs` - Enum for compression methods
-- `ArchiveEncoding.cs` - Character encoding configuration
-- `ExtractionOptions.cs` - Extraction configuration
-- Format-specific headers: `Zip/Headers/`, `Tar/Headers/`, `Rar/Headers/`, etc.
-
-#### `Compressors/` - Compression Algorithms
-Low-level compression streams implementing specific algorithms.
-
-**Algorithms:**
-- `Deflate/` - DEFLATE compression (Zip default)
-- `BZip2/` - BZip2 compression
-- `LZMA/` - LZMA compression (7Zip, XZ, LZip)
-- `PPMd/` - Prediction by Partial Matching (Zip, 7Zip)
-- `ZStandard/` - ZStandard compression (decompression only)
-- `Xz/` - XZ format (decompression only)
-- `Rar/` - RAR-specific unpacking
-- `Arj/`, `Arc/`, `Ace/` - Legacy format decompression
-- `Filters/` - BCJ/BCJ2 filters for executable compression
-
-**Each Compressor:**
-- Implements a `Stream` subclass
-- Provides both compression and decompression
-- Some are read-only (decompression only)
-
-#### `Crypto/` - Encryption & Hashing
-Cryptographic functions and stream wrappers.
-
-**Key Files:**
-- `Crc32Stream.cs` - CRC32 calculation wrapper
-- `BlockTransformer.cs` - Block cipher transformations
-- AES, PKWare, WinZip encryption implementations
-
-#### `IO/` - Stream Utilities
-Stream wrappers and utilities.
-
-**Key Classes:**
-- `SharpCompressStream` - Base stream class
-- `ProgressReportingStream` - Progress tracking wrapper
-- `MarkingBinaryReader` - Binary reader with position marks
-- `BufferedSubStream` - Buffered read-only substream
-- `ReadOnlySubStream` - Read-only view of parent stream
-- `NonDisposingStream` - Prevents wrapped stream disposal
-

-
-## Design Patterns
-
-### 1. Factory Pattern
-
-**Purpose:** Auto-detect format and create appropriate reader/writer.
-
-**Example:**
-```csharp
-// User calls factory
-using (var reader = ReaderFactory.Open(stream))  // Returns IReader
-{
-    while (reader.MoveToNextEntry())
-    {
-        // Process entry
-    }
-}
-
-// Behind the scenes:
-// 1. Factory.Open() probes stream signatures
-// 2. Detects format (Zip, Tar, Rar, etc.)
-// 3. Creates appropriate reader (ZipReader, TarReader, etc.)
-// 4. Returns as generic IReader interface
-```
-
-**Files:**
-- `src/SharpCompress/Factories/ReaderFactory.cs`
-- `src/SharpCompress/Factories/WriterFactory.cs`
-- `src/SharpCompress/Factories/ArchiveFactory.cs`
-
-### 2. Strategy Pattern
-
-**Purpose:** Encapsulate compression algorithms as swappable strategies.
-
-**Example:**
-```csharp
-// Different compression strategies
-CompressionType.Deflate     // DEFLATE
-CompressionType.BZip2       // BZip2
-CompressionType.LZMA        // LZMA
-CompressionType.PPMd        // PPMd
-
-// Writer uses strategy pattern
-var archive = ZipArchive.Create();
-archive.SaveTo("output.zip", CompressionType.Deflate);   // Use Deflate
-archive.SaveTo("output.bz2", CompressionType.BZip2);    // Use BZip2
-```
-
-**Files:**
-- `src/SharpCompress/Compressors/` - Strategy implementations
-
-### 3. Decorator Pattern
-
-**Purpose:** Wrap streams with additional functionality.
-
-**Example:**
-```csharp
-// Progress reporting decorator
-var progressStream = new ProgressReportingStream(baseStream, progressReporter);
-progressStream.Read(buffer, 0, buffer.Length);  // Reports progress
-
-// Non-disposing decorator
-var nonDisposingStream = new NonDisposingStream(baseStream);
-using (var compressor = new DeflateStream(nonDisposingStream))
-{
-    // baseStream won't be disposed when compressor is disposed
-}
-```
-
-**Files:**
-- `src/SharpCompress/IO/ProgressReportingStream.cs`
-- `src/SharpCompress/IO/NonDisposingStream.cs`
-
-### 4. Template Method Pattern
-
-**Purpose:** Define algorithm skeleton in base class, let subclasses fill details.
-
-**Example:**
-```csharp
-// AbstractArchive defines common archive operations
-public abstract class AbstractArchive : IArchive
-{
-    // Template methods
-    public virtual void WriteToDirectory(string destinationDirectory, ExtractionOptions options)
-    {
-        // Common extraction logic
-        foreach (var entry in Entries)
-        {
-            // Call subclass method
-            entry.WriteToFile(destinationPath, options);
-        }
-    }
-    
-    // Subclasses override format-specific details
-    protected abstract Entry CreateEntry(EntryData data);
-}
-```
-
-**Files:**
-- `src/SharpCompress/Archives/AbstractArchive.cs`
-- `src/SharpCompress/Readers/AbstractReader.cs`
-
-### 5. Iterator Pattern
-
-**Purpose:** Provide sequential access to entries.
-
-**Example:**
-```csharp
-// Archive API - provides collection
-IEnumerable<IEntry> entries = archive.Entries;
-foreach (var entry in entries)
-{
-    // Random access - entries already in memory
-}
-
-// Reader API - provides iterator
-IReader reader = ReaderFactory.Open(stream);
-while (reader.MoveToNextEntry())
-{
-    // Forward-only iteration - one entry at a time
-    var entry = reader.Entry;
-}
-```
-
----
-

-    
-    void WriteToFile(string fullPath, ExtractionOptions options = null);
-    void WriteToStream(Stream destinationStream);
-    Stream OpenEntryStream();
-    
-    // ... async variants

-
-## Adding Support for a New Format
-
-### Step 1: Understand the Format
-- Research format specification
-- Understand compression/encryption used
-- Study existing similar formats in codebase
-
-### Step 2: Create Format Structure Classes
-
-**Create:** `src/SharpCompress/Common/NewFormat/`
-
-```csharp
-// Headers and data structures
-public class NewFormatHeader
-{
-    public uint Magic { get; set; }
-    public ushort Version { get; set; }
-    // ... other fields
-    
-    public static NewFormatHeader Read(BinaryReader reader)
-    {
-        // Deserialize from binary
-    }
-}
-
-public class NewFormatEntry
-{
-    public string FileName { get; set; }
-    public uint CompressedSize { get; set; }
-    public uint UncompressedSize { get; set; }
-    // ... other fields
-}
-```
-
-### Step 3: Create Archive Implementation
-
-**Create:** `src/SharpCompress/Archives/NewFormat/NewFormatArchive.cs`
-
-```csharp
-public class NewFormatArchive : AbstractArchive
-{
-    private NewFormatHeader _header;
-    private List<NewFormatEntry> _entries;
-    
-    public static NewFormatArchive Open(Stream stream)
-    {
-        var archive = new NewFormatArchive();
-        archive._header = NewFormatHeader.Read(stream);
-        archive.LoadEntries(stream);
-        return archive;
-    }
-    
-    public override IEnumerable<IEntry> Entries => _entries.Select(e => new Entry(e));
-    
-    protected override Stream OpenEntryStream(Entry entry)
-    {
-        // Return decompressed stream for entry
-    }
-    
-    // ... other abstract method implementations
-}
-```
-
-### Step 4: Create Reader Implementation
-
-**Create:** `src/SharpCompress/Readers/NewFormat/NewFormatReader.cs`
-
-```csharp
-public class NewFormatReader : AbstractReader
-{
-    private NewFormatHeader _header;
-    private BinaryReader _reader;
-    
-    public NewFormatReader(Stream stream)
-    {
-        _reader = new BinaryReader(stream);
-        _header = NewFormatHeader.Read(_reader);
-    }
-    
-    public override bool MoveToNextEntry()
-    {
-        // Read next entry header
-        if (!_reader.BaseStream.CanRead) return false;
-        
-        var entryData = NewFormatEntry.Read(_reader);
-        // ... set this.Entry
-        return entryData != null;
-    }
-    
-    // ... other abstract method implementations
-}
-```
-
-### Step 5: Create Factory
-
-**Create:** `src/SharpCompress/Factories/NewFormatFactory.cs`
-
-```csharp
-public class NewFormatFactory : Factory, IArchiveFactory, IReaderFactory
-{
-    // Archive format magic bytes (signature)
-    private static readonly byte[] NewFormatSignature = new byte[] { 0x4E, 0x46 };  // "NF"
-    
-    public static NewFormatFactory Instance { get; } = new();
-    
-    public IArchive CreateArchive(Stream stream) 
-        => NewFormatArchive.Open(stream);
-    
-    public IReader CreateReader(Stream stream, ReaderOptions options)
-        => new NewFormatReader(stream) { Options = options };
-    
-    public bool Matches(Stream stream, ReadOnlySpan<byte> signature) 
-        => signature.StartsWith(NewFormatSignature);
-}
-```
-
-### Step 6: Register Factory
-
-**Update:** `src/SharpCompress/Factories/ArchiveFactory.cs`
-
-```csharp
-private static readonly IFactory[] Factories = 
-{
-    ZipFactory.Instance,
-    TarFactory.Instance,
-    RarFactory.Instance,
-    SevenZipFactory.Instance,
-    GZipFactory.Instance,
-    NewFormatFactory.Instance,  // Add here
-    // ... other factories
-};
-```
-
-### Step 7: Add Tests
-
-**Create:** `tests/SharpCompress.Test/NewFormat/NewFormatTests.cs`
-
-```csharp
-public class NewFormatTests : TestBase
-{
-    [Fact]
-    public void NewFormat_Extracts_Successfully()
-    {
-        var archivePath = Path.Combine(TEST_ARCHIVES_PATH, "archive.newformat");
-        using (var archive = NewFormatArchive.Open(archivePath))
-        {
-            archive.WriteToDirectory(SCRATCH_FILES_PATH);
-            // Assert extraction
-        }
-    }
-    
-    [Fact]
-    public void NewFormat_Reader_Works()
-    {
-        var archivePath = Path.Combine(TEST_ARCHIVES_PATH, "archive.newformat");
-        using (var stream = File.OpenRead(archivePath))
-        using (var reader = new NewFormatReader(stream))
-        {
-            Assert.True(reader.MoveToNextEntry());
-            Assert.NotNull(reader.Entry);
-        }
-    }
-}
-```
-
-### Step 8: Add Test Archives
-
-Place test files in `tests/TestArchives/Archives/NewFormat/` directory.
-
-### Step 9: Document
-
-Update `docs/FORMATS.md` with format support information.
-

-
-## Compression Algorithm Implementation
-
-### Creating a New Compression Stream
-
-**Example:** Creating `CustomStream` for a custom compression algorithm
-
-```csharp
-public class CustomStream : Stream
-{
-    private readonly Stream _baseStream;
-    private readonly bool _leaveOpen;
-    
-    public CustomStream(Stream baseStream, bool leaveOpen = false)
-    {
-        _baseStream = baseStream;
-        _leaveOpen = leaveOpen;
-    }
-    
-    public override int Read(byte[] buffer, int offset, int count)
-    {
-        // Decompress data from _baseStream into buffer
-        // Return number of decompressed bytes
-    }
-    
-    public override void Write(byte[] buffer, int offset, int count)
-    {
-        // Compress data from buffer into _baseStream
-    }
-    
-    protected override void Dispose(bool disposing)
-    {
-        if (disposing && !_leaveOpen)
-        {
-            _baseStream?.Dispose();
-        }
-        base.Dispose(disposing);
-    }
-}
-```
-
----
-
-## Stream Handling Best Practices
-
-### Disposal Pattern
-
-```csharp
-// Correct: Nested using blocks
-using (var fileStream = File.OpenRead("archive.zip"))
-using (var archive = ZipArchive.Open(fileStream))
-{
-    archive.WriteToDirectory(@"C:\output");
-}
-// Both archive and fileStream properly disposed
-
-// Correct: Using with options
-var options = new ReaderOptions { LeaveStreamOpen = true };
-var stream = File.OpenRead("archive.zip");
-using (var archive = ZipArchive.Open(stream, options))
-{
-    archive.WriteToDirectory(@"C:\output");
-}
-stream.Dispose();  // Manually dispose if LeaveStreamOpen = true
-```
-
-### NonDisposingStream Wrapper
-
-```csharp
-// Prevent unwanted stream closure
-var baseStream = File.OpenRead("data.bin");
-var nonDisposing = new NonDisposingStream(baseStream);
-
-using (var compressor = new DeflateStream(nonDisposing))
-{
-    // Compressor won't close baseStream when disposed
-}
-
-// baseStream still usable
-baseStream.Position = 0;  // Works
-baseStream.Dispose();  // Manual disposal
-```
-
----
-
-## Performance Considerations
-
-### Memory Efficiency
-
-1. **Avoid loading entire archive in memory** - Use Reader API for large files
-2. **Process entries sequentially** - Especially for solid archives
-3. **Use appropriate buffer sizes** - Larger buffers for network I/O
-4. **Dispose streams promptly** - Free resources when done
-
-### Algorithm Selection
-
-1. **Archive API** - Fast for small archives with random access
-2. **Reader API** - Efficient for large files or streaming
-3. **Solid archives** - Sequential extraction much faster
-4. **Compression levels** - Trade-off between speed and size
-
----
-
-## Testing Guidelines
-
-### Test Coverage
-
-1. **Happy path** - Normal extraction works
-2. **Edge cases** - Empty archives, single file, many files
-3. **Corrupted data** - Handle gracefully
-4. **Error cases** - Missing passwords, unsupported compression
-5. **Async operations** - Both sync and async code paths
-
-### Test Archives
-
-- Use `tests/TestArchives/` for test data
-- Create format-specific subdirectories
-- Include encrypted, corrupted, and edge case archives
-- Don't recreate existing archives
-
-### Test Patterns
-
-```csharp
-[Fact]
-public void Archive_Extraction_Works()
-{
-    // Arrange
-    var testArchive = Path.Combine(TEST_ARCHIVES_PATH, "test.zip");
-    
-    // Act
-    using (var archive = ZipArchive.Open(testArchive))
-    {
-        archive.WriteToDirectory(SCRATCH_FILES_PATH);
-    }
-    
-    // Assert
-    Assert.True(File.Exists(Path.Combine(SCRATCH_FILES_PATH, "file.txt")));
-}
-```

-# SharpCompress Character Encoding Guide
-
-This guide explains how SharpCompress handles character encoding for archive entries (filenames, comments, etc.).
-
-## Overview
-
-Most archive formats store filenames and metadata as bytes. SharpCompress must convert these bytes to strings using the appropriate character encoding.
-
-**Common Problem:** Archives created on systems with non-UTF8 encodings (especially Japanese, Chinese systems) appear with corrupted filenames when extracted on systems that assume UTF8.
-
----
-
-## ArchiveEncoding Class
-
-### Basic Usage
-
-```csharp
-using SharpCompress.Common;
-using SharpCompress.Readers;
-
-// Configure encoding before opening archive
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding(932)  // cp932 for Japanese
-    }
-};
-
-using (var archive = ZipArchive.Open("japanese.zip", options))
-{
-    foreach (var entry in archive.Entries)
-    {
-        Console.WriteLine(entry.Key);  // Now shows correct characters
-    }
-}
-```
-
-### ArchiveEncoding Properties
-
-| Property | Purpose |
-|----------|---------|
-| `Default` | Default encoding for filenames (fallback) |
-| `CustomDecoder` | Custom decoding function for special cases |
-
-### Setting for Different APIs
-
-**Archive API:**
-```csharp
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding { Default = Encoding.GetEncoding(932) }
-};
-using (var archive = ZipArchive.Open("file.zip", options))
-{
-    // Use archive with correct encoding
-}
-```
-
-**Reader API:**
-```csharp
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding { Default = Encoding.GetEncoding(932) }
-};
-using (var stream = File.OpenRead("file.zip"))
-using (var reader = ReaderFactory.Open(stream, options))
-{
-    while (reader.MoveToNextEntry())
-    {
-        // Filenames decoded correctly
-    }
-}
-```
-
----
-
-## Common Encodings
-
-### Asian Encodings
-
-#### cp932 (Japanese)
-```csharp
-// Windows-31J, Shift-JIS variant used on Japanese Windows
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding(932)
-    }
-};
-using (var archive = ZipArchive.Open("japanese.zip", options))
-{
-    // Correctly decodes Japanese filenames
-}
-```
-
-**When to use:**
-- Archives from Japanese Windows systems
-- Files with Japanese characters in names
-
-#### gb2312 (Simplified Chinese)
-```csharp
-// Simplified Chinese
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("gb2312")
-    }
-};
-```
-
-#### gbk (Extended Simplified Chinese)
-```csharp
-// Extended Simplified Chinese (more characters than gb2312)
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("gbk")
-    }
-};
-```
-
-#### big5 (Traditional Chinese)
-```csharp
-// Traditional Chinese (Taiwan, Hong Kong)
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("big5")
-    }
-};
-```
-
-#### euc-jp (Japanese, Unix)
-```csharp
-// Extended Unix Code for Japanese
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("eucjp")
-    }
-};
-```
-
-#### euc-kr (Korean)
-```csharp
-// Extended Unix Code for Korean
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("euc-kr")
-    }
-};
-```
-
-### Western European Encodings
-
-#### iso-8859-1 (Latin-1)
-```csharp
-// Western European (includes accented characters)
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("iso-8859-1")
-    }
-};
-```
-
-**When to use:**
-- Archives from French, German, Spanish systems
-- Files with accented characters (é, ñ, ü, etc.)
-
-#### cp1252 (Windows-1252)
-```csharp
-// Windows Western European
-// Very similar to iso-8859-1 but with additional printable characters
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("cp1252")
-    }
-};
-```
-
-**When to use:**
-- Archives from older Western European Windows systems
-- Files with smart quotes and other Windows-specific characters
-
-#### iso-8859-15 (Latin-9)
-```csharp
-// Western European with Euro symbol support
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("iso-8859-15")
-    }
-};
-```
-
-### Cyrillic Encodings
-
-#### cp1251 (Windows Cyrillic)
-```csharp
-// Russian, Serbian, Bulgarian, etc.
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("cp1251")
-    }
-};
-```
-
-#### koi8-r (KOI8 Russian)
-```csharp
-// Russian (Unix standard)
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("koi8-r")
-    }
-};
-```
-
-### UTF Encodings (Modern)
-
-#### UTF-8 (Default)
-```csharp
-// Modern standard - usually correct for new archives
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.UTF8
-    }
-};
-```
-
-#### UTF-16
-```csharp
-// Unicode - rarely used in archives
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.Unicode
-    }
-};
-```
-
----
-
-## Encoding Auto-Detection
-
-SharpCompress attempts to auto-detect encoding, but this isn't always reliable:
-
-```csharp
-// Auto-detection (default)
-using (var archive = ZipArchive.Open("file.zip"))  // Uses UTF8 by default
-{
-    // May show corrupted characters if archive uses different encoding
-}
-
-// Explicit encoding (more reliable)
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding { Default = Encoding.GetEncoding(932) }
-};
-using (var archive = ZipArchive.Open("file.zip", options))
-{
-    // Correct characters displayed
-}
-```
-
-### When Manual Override is Needed
-
-| Situation | Solution |
-|-----------|----------|
-| Archive shows corrupted characters | Specify the encoding explicitly |
-| Archives from specific region | Use that region's encoding |
-| Mixed encodings in archive | Use CustomDecoder |
-| Testing with international files | Try different encodings |
-
----
-
-## Custom Decoder
-
-For complex scenarios where a single encoding isn't sufficient:
-
-### Basic Custom Decoder
-
-```csharp
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding
-    {
-        CustomDecoder = (data, offset, length) =>
-        {
-            // Custom decoding logic
-            var bytes = new byte[length];
-            Array.Copy(data, offset, bytes, 0, length);
-            
-            // Try UTF8 first
-            try
-            {
-                return Encoding.UTF8.GetString(bytes);
-            }
-            catch
-            {
-                // Fallback to cp932 if UTF8 fails
-                return Encoding.GetEncoding(932).GetString(bytes);
-            }
-        }
-    }
-};
-
-using (var archive = ZipArchive.Open("mixed.zip", options))
-{
-    foreach (var entry in archive.Entries)
-    {
-        Console.WriteLine(entry.Key);  // Uses custom decoder
-    }
-}
-```
-
-### Advanced: Detect Encoding by Content
-
-```csharp
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding
-    {
-        CustomDecoder = DetectAndDecode
-    }
-};
-
-private static string DetectAndDecode(byte[] data, int offset, int length)
-{
-    var bytes = new byte[length];
-    Array.Copy(data, offset, bytes, 0, length);
-    
-    // Try UTF8 (most modern archives)
-    try
-    {
-        var str = Encoding.UTF8.GetString(bytes);
-        // Verify it decoded correctly (no replacement characters)
-        if (!str.Contains('\uFFFD'))
-            return str;
-    }
-    catch { }
-    
-    // Try cp932 (Japanese)
-    try
-    {
-        var str = Encoding.GetEncoding(932).GetString(bytes);
-        if (!str.Contains('\uFFFD'))
-            return str;
-    }
-    catch { }
-    
-    // Fallback to iso-8859-1 (always succeeds)
-    return Encoding.GetEncoding("iso-8859-1").GetString(bytes);
-}
-```
-
----
-
-## Code Examples
-
-### Extract Archive with Japanese Filenames
-
-```csharp
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding(932)  // cp932
-    }
-};
-
-using (var archive = ZipArchive.Open("japanese_files.zip", options))
-{
-    archive.WriteToDirectory(@"C:\output", new ExtractionOptions
-    {
-        ExtractFullPath = true,
-        Overwrite = true
-    });
-}
-// Files extracted with correct Japanese names
-```
-
-### Extract Archive with Western European Filenames
-
-```csharp
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("iso-8859-1")
-    }
-};
-
-using (var archive = ZipArchive.Open("french_files.zip", options))
-{
-    archive.WriteToDirectory(@"C:\output");
-}
-// Accented characters (é, è, ê, etc.) display correctly
-```
-
-### Extract Archive with Chinese Filenames
-
-```csharp
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("gbk")  // Simplified Chinese
-    }
-};
-
-using (var archive = ZipArchive.Open("chinese_files.zip", options))
-{
-    archive.WriteToDirectory(@"C:\output");
-}
-```
-
-### Extract Archive with Russian Filenames
-
-```csharp
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("cp1251")  // Windows Cyrillic
-    }
-};
-
-using (var archive = ZipArchive.Open("russian_files.zip", options))
-{
-    archive.WriteToDirectory(@"C:\output");
-}
-```
-
-### Reader API with Encoding
-
-```csharp
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding(932)
-    }
-};
-
-using (var stream = File.OpenRead("japanese.zip"))
-using (var reader = ReaderFactory.Open(stream, options))
-{
-    while (reader.MoveToNextEntry())
-    {
-        if (!reader.Entry.IsDirectory)
-        {
-            Console.WriteLine(reader.Entry.Key);  // Correct characters
-            reader.WriteEntryToDirectory(@"C:\output");
-        }
-    }
-}
-```
-
----
-
-## Creating Archives with Correct Encoding
-
-When creating archives, SharpCompress uses UTF8 by default (recommended):
-
-```csharp
-// Create with UTF8 (default, recommended)
-using (var archive = ZipArchive.Create())
-{
-    archive.AddAllFromDirectory(@"D:\my_files");
-    archive.SaveTo("output.zip", CompressionType.Deflate);
-    // Archives created with UTF8 encoding
-}
-```
-
-If you need to create archives for systems that expect specific encodings:
-
-```csharp
-// Note: SharpCompress Writer API uses UTF8 for encoding
-// To create archives with other encodings, consider:
-// 1. Let users on those systems create archives
-// 2. Use system tools (7-Zip, WinRAR) with desired encoding
-// 3. Post-process archives if absolutely necessary
-
-// For now, recommend modern UTF8-based archives
-```
-

-
-## Troubleshooting Encoding Issues
-
-### Filenames Show Question Marks (?)
-
-```
-✗ Wrong encoding detected
-test文件.txt → test???.txt
-```
-
-**Solution:** Specify correct encoding explicitly
-
-```csharp
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding 
-    { 
-        Default = Encoding.GetEncoding("gbk")  // Try different encodings
-    }
-};
-```
-
-### Filenames Show Replacement Character (￿)
-
-```
-✗ Invalid bytes for selected encoding
-café.txt → caf￿.txt
-```
-
-**Solution:**
-1. Try a different encoding (see Common Encodings table)
-2. Use CustomDecoder with fallback encoding
-3. Archive might be corrupted
-
-### Mixed Encodings in Single Archive
-
-```csharp
-// Use CustomDecoder to handle mixed encodings
-var options = new ReaderOptions
-{
-    ArchiveEncoding = new ArchiveEncoding
-    {
-        CustomDecoder = (data, offset, length) =>
-        {
-            // Try multiple encodings in priority order
-            var bytes = new byte[length];
-            Array.Copy(data, offset, bytes, 0, length);
-            
-            foreach (var encoding in new[] 
-            {
-                Encoding.UTF8,
-                Encoding.GetEncoding(932),
-                Encoding.GetEncoding("iso-8859-1")
-            })
-            {
-                try
-                {
-                    var str = encoding.GetString(bytes);
-                    if (!str.Contains('\uFFFD'))
-                        return str;
-                }
-                catch { }
-            }
-            
-            // Final fallback
-            return Encoding.GetEncoding("iso-8859-1").GetString(bytes);
-        }
-    }
-};
-```

-## Encoding Reference Table
-
-| Encoding | Code | Use Case |
-|----------|------|----------|
-| UTF-8 | (default) | Modern archives, recommended |
-| cp932 | 932 | Japanese Windows |
-| gb2312 | "gb2312" | Simplified Chinese |
-| gbk | "gbk" | Extended Simplified Chinese |
-| big5 | "big5" | Traditional Chinese |
-| iso-8859-1 | "iso-8859-1" | Western European |

-
-## Best Practices
-
-1. **Use UTF-8 for new archives** - Most modern systems support it
-2. **Ask the archive creator** - When receiving archives with corrupted names
-3. **Provide encoding options** - If your app handles user archives
-4. **Document your assumption** - Tell users what encoding you're using
-5. **Test with international files** - Before releasing production code

-
-1. SOLID Rars are only supported in the RarReader API.
-2. Zip format supports pkware and WinzipAES encryption. However, encrypted LZMA is not supported. Zip64 reading/writing is supported but only with seekable streams as the Zip spec doesn't support Zip64 data in post data descriptors. Deflate64 is only supported for reading. See [Zip Format Notes](#zip-format-notes) for details on multi-volume archives and streaming behavior.
-3. The Tar format requires a file size in the header. If no size is specified to the TarWriter and the stream is not seekable, then an exception will be thrown.
-4. The 7Zip format doesn't allow for reading as a forward-only stream so 7Zip is only supported through the Archive API. See [7Zip Format Notes](#7zip-format-notes) for details on async extraction behavior.
-5. LZip has no support for extra data like the file name or timestamp. There is a default filename used when looking at the entry Key on the archive.
-
-### Zip Format Notes
-
-- Multi-volume/split ZIP archives require ZipArchive (seekable streams) as ZipReader cannot seek across volume files.
-- ZipReader processes entries from LocalEntry headers (which include directory entries ending with `/`) and intentionally skips DirectoryEntry headers from the central directory, as they are redundant in streaming mode - all entry data comes from LocalEntry headers which ZipReader has already processed.
-
-### 7Zip Format Notes
-
-- **Async Extraction Performance**: When using async extraction methods (e.g., `ExtractAllEntries()` with `MoveToNextEntryAsync()`), each file creates its own decompression stream to avoid state corruption in the LZMA decoder. This is less efficient than synchronous extraction, which can reuse a single decompression stream for multiple files in the same folder.
-  
-  **Performance Impact**: For archives with many small files in the same compression folder, async extraction will be slower than synchronous extraction because it must:
-  1. Create a new LZMA decoder for each file
-  2. Skip through the decompressed data to reach each file's starting position
-  
-  **Recommendation**: For best performance with 7Zip archives, use synchronous extraction methods (`MoveToNextEntry()` and `WriteEntryToDirectory()`) when possible. Use async methods only when you need to avoid blocking the thread (e.g., in UI applications or async-only contexts).
-  
-  **Technical Details**: 7Zip archives group files into "folders" (compression units), where all files in a folder share one continuous LZMA-compressed stream. The LZMA decoder maintains internal state (dictionary window, decoder positions) that assumes sequential, non-interruptible processing. Async operations can yield control during awaits, which would corrupt this shared state. To avoid this, async extraction creates a fresh decoder stream for each file.
-
-## Compression Streams
-
-For those who want to directly compress/decompress bits. The single file formats are represented here as well. However, BZip2, LZip and XZ have no metadata (GZip has a little) so using them without something like a Tar file makes little sense.
-
-| Compressor      | Compress/Decompress |
-| --------------- | ------------------- |
-| BZip2Stream     | Both                |
-| GZipStream      | Both                |
-| DeflateStream   | Both                |
-| Deflate64Stream | Decompress          |
-| LZMAStream      | Both                |
-| PPMdStream      | Both                |
-| ADCStream       | Decompress          |
-| LZipStream      | Both                |
-| XZStream        | Decompress          |
-| ZStandardStream | Decompress          |
-
-## Archive Formats vs Compression
-
-Sometimes the terminology gets mixed.
-
-### Compression
-
-DEFLATE, LZMA are pure compression algorithms
-
-### Formats
-
-Formats like Zip, 7Zip, Rar are archive formats only. They use other compression methods (e.g. DEFLATE, LZMA, etc.) or propriatory (e.g RAR)
-
-### Overlap
-
-GZip, BZip2 and LZip are single file archival formats. The overlap in the API happens because Tar uses the single file formats as "compression" methods and the API tries to hide this a bit.

-# SharpCompress Performance Guide
-
-This guide helps you optimize SharpCompress for performance in various scenarios.
-
-## API Selection Guide
-
-### Archive API vs Reader API
-
-Choose the right API based on your use case:
-
-| Aspect | Archive API | Reader API |
-|--------|------------|-----------|
-| **Stream Type** | Seekable only | Non-seekable OK |
-| **Memory Usage** | All entries in memory | One entry at a time |
-| **Random Access** | ✓ Yes | ✗ No |
-| **Best For** | Small-to-medium archives | Large or streaming data |
-| **Performance** | Fast for random access | Better for large files |
-
-### Archive API (Fast for Random Access)
-
-```csharp
-// Use when:
-// - Archive fits in memory
-// - You need random access to entries
-// - Stream is seekable (file, MemoryStream)
-
-using (var archive = ZipArchive.Open("archive.zip"))
-{
-    // Random access - all entries available
-    var specific = archive.Entries.FirstOrDefault(e => e.Key == "file.txt");
-    if (specific != null)
-    {
-        specific.WriteToFile(@"C:\output\file.txt");
-    }
-}
-```
-
-**Performance Characteristics:**
-- ✓ Instant entry lookup
-- ✓ Parallel extraction possible
-- ✗ Entire archive in memory
-- ✗ Can't process while downloading
-
-### Reader API (Best for Large Files)
-
-```csharp
-// Use when:
-// - Processing large archives (>100 MB)
-// - Streaming from network/pipe
-// - Memory is constrained
-// - Forward-only processing is acceptable
-
-using (var stream = File.OpenRead("large.zip"))
-using (var reader = ReaderFactory.Open(stream))
-{
-    while (reader.MoveToNextEntry())
-    {
-        // Process one entry at a time
-        reader.WriteEntryToDirectory(@"C:\output");
-    }
-}
-```
-
-**Performance Characteristics:**
-- ✓ Minimal memory footprint
-- ✓ Works with non-seekable streams
-- ✓ Can process while downloading
-- ✗ Forward-only (no random access)
-- ✗ Entry lookup requires iteration

-
-## Buffer Sizing
-
-### Understanding Buffers
-
-SharpCompress uses internal buffers for reading compressed data. Buffer size affects:
-- **Speed:** Larger buffers = fewer I/O operations = faster
-- **Memory:** Larger buffers = higher memory usage
-
-### Recommended Buffer Sizes
-
-| Scenario | Size | Notes |
-|----------|------|-------|
-| Embedded/IoT devices | 4-8 KB | Minimal memory usage |
-| Memory-constrained | 16-32 KB | Conservative default |
-| Standard use (default) | 64 KB | Recommended default |
-| Large file streaming | 256 KB | Better throughput |
-| High-speed SSD | 512 KB - 1 MB | Maximum throughput |
-
-### How Buffer Size Affects Performance
-
-```csharp
-// SharpCompress manages buffers internally
-// You can't directly set buffer size, but you can:
-
-// 1. Use Stream.CopyTo with explicit buffer size
-using (var entryStream = reader.OpenEntryStream())
-using (var fileStream = File.Create(@"C:\output\file.txt"))
-{
-    // 64 KB buffer (default)
-    entryStream.CopyTo(fileStream);
-    
-    // Or specify larger buffer for faster copy
-    entryStream.CopyTo(fileStream, bufferSize: 262144);  // 256 KB
-}
-
-// 2. Use custom buffer for writing
-using (var entryStream = reader.OpenEntryStream())
-using (var fileStream = File.Create(@"C:\output\file.txt"))
-{
-    byte[] buffer = new byte[262144];  // 256 KB
-    int bytesRead;
-    while ((bytesRead = entryStream.Read(buffer, 0, buffer.Length)) > 0)
-    {
-        fileStream.Write(buffer, 0, bytesRead);
-    }
-}
-```
-
----
-
-## Streaming Large Files
-
-### Non-Seekable Stream Patterns
-
-For processing archives from downloads or pipes:
-
-```csharp
-// Download stream (non-seekable)
-using (var httpStream = await httpClient.GetStreamAsync(url))
-using (var reader = ReaderFactory.Open(httpStream))
-{
-    // Process entries as they arrive
-    while (reader.MoveToNextEntry())
-    {
-        if (!reader.Entry.IsDirectory)
-        {
-            reader.WriteEntryToDirectory(@"C:\output");
-        }
-    }
-}
-```
-
-**Performance Tips:**
-- Don't try to buffer the entire stream
-- Process entries immediately
-- Use async APIs for better responsiveness
-
-### Download-Then-Extract vs Streaming
-
-Choose based on your constraints:
-
-| Approach | When to Use |
-|----------|------------|
-| **Download then extract** | Moderate size, need random access |
-| **Stream during download** | Large files, bandwidth limited, memory constrained |
-
-```csharp
-// Download then extract (requires disk space)
-var archivePath = await DownloadFile(url, @"C:\temp\archive.zip");
-using (var archive = ZipArchive.Open(archivePath))
-{
-    archive.WriteToDirectory(@"C:\output");
-}
-
-// Stream during download (on-the-fly extraction)
-using (var httpStream = await httpClient.GetStreamAsync(url))
-using (var reader = ReaderFactory.Open(httpStream))
-{
-    while (reader.MoveToNextEntry())
-    {
-        reader.WriteEntryToDirectory(@"C:\output");
-    }
-}
-```
-
----
-
-## Solid Archive Optimization
-
-### Why Solid Archives Are Slow
-
-Solid archives (Rar, 7Zip) group files together in a single compressed stream:
-
-```
-Solid Archive Layout:
-[Header] [Compressed Stream] [Footer]
-         ├─ File1 compressed data
-         ├─ File2 compressed data
-         ├─ File3 compressed data
-         └─ File4 compressed data
-```
-
-Extracting File3 requires decompressing File1 and File2 first.
-
-### Sequential vs Random Extraction
-
-**Random Extraction (Slow):**
-```csharp
-using (var archive = RarArchive.Open("solid.rar"))
-{
-    foreach (var entry in archive.Entries)
-    {
-        entry.WriteToFile(@"C:\output\" + entry.Key);  // ✗ Slow!
-        // Each entry triggers full decompression from start
-    }
-}
-```
-
-**Sequential Extraction (Fast):**
-```csharp
-using (var archive = RarArchive.Open("solid.rar"))
-{
-    // Method 1: Use WriteToDirectory (recommended)
-    archive.WriteToDirectory(@"C:\output", new ExtractionOptions
-    {
-        ExtractFullPath = true,
-        Overwrite = true
-    });
-    
-    // Method 2: Use ExtractAllEntries
-    archive.ExtractAllEntries();
-    
-    // Method 3: Use Reader API (also sequential)
-    using (var reader = RarReader.Open(File.OpenRead("solid.rar")))
-    {
-        while (reader.MoveToNextEntry())
-        {
-            reader.WriteEntryToDirectory(@"C:\output");
-        }
-    }
-}
-```

-- Random extraction: O(n²) - very slow for many files
-- Sequential extraction: O(n) - 10-100x faster
-
-### Best Practices for Solid Archives
-
-1. **Always extract sequentially** when possible
-2. **Use Reader API** for large solid archives
-3. **Process entries in order** from the archive
-4. **Consider using 7Zip command-line** for scripted extractions

-
-## Compression Level Trade-offs
-
-### Deflate/GZip Levels
-
-```csharp
-// Level 1 = Fastest, largest size
-// Level 6 = Default (balanced)
-// Level 9 = Slowest, best compression
-
-// Write with different compression levels
-using (var archive = ZipArchive.Create())
-{
-    archive.AddAllFromDirectory(@"D:\data");
-    
-    // Fast compression (level 1)
-    archive.SaveTo("fast.zip", new WriterOptions(CompressionType.Deflate)
-    {
-        CompressionLevel = 1
-    });
-    
-    // Default compression (level 6)
-    archive.SaveTo("default.zip", CompressionType.Deflate);
-    
-    // Best compression (level 9)
-    archive.SaveTo("best.zip", new WriterOptions(CompressionType.Deflate)
-    {
-        CompressionLevel = 9
-    });
-}
-```
-
-**Speed vs Size:**
-| Level | Speed | Size | Use Case |
-|-------|-------|------|----------|
-| 1 | 10x | 90% | Network, streaming |
-| 6 | 1x | 75% | Default (good balance) |
-| 9 | 0.1x | 65% | Archival, static storage |
-
-### BZip2 Block Size
-
-```csharp
-// BZip2 block size affects memory and compression
-// 100K to 900K (default 900K)
-
-// Smaller block size = lower memory, faster
-// Larger block size = better compression, slower
-
-using (var archive = TarArchive.Create())
-{
-    archive.AddAllFromDirectory(@"D:\data");
-    
-    // These are preset in WriterOptions via CompressionLevel
-    archive.SaveTo("archive.tar.bz2", CompressionType.BZip2);
-}
-```
-
-### LZMA Settings
-
-LZMA compression is very powerful but memory-intensive:
-
-```csharp
-// LZMA (7Zip, .tar.lzma):
-// - Dictionary size: 16 KB to 1 GB (default 32 MB)
-// - Faster preset: smaller dictionary
-// - Better compression: larger dictionary
-
-// Preset via CompressionType
-using (var archive = TarArchive.Create())
-{
-    archive.AddAllFromDirectory(@"D:\data");
-    archive.SaveTo("archive.tar.xz", CompressionType.LZMA);  // Default settings
-}
-```

-## Async Performance
-
-### When Async Helps
-
-Async is beneficial when:
-- **Long I/O operations** (network, slow disks)
-- **UI responsiveness** needed (Windows Forms, WPF, Blazor)
-- **Server applications** (ASP.NET, multiple concurrent operations)
-
-```csharp
-// Async extraction (non-blocking)
-using (var archive = ZipArchive.Open("archive.zip"))
-{
-    await archive.WriteToDirectoryAsync(
-        @"C:\output",
-        new ExtractionOptions { ExtractFullPath = true, Overwrite = true },
-        cancellationToken
-    );
-}
-// Thread can handle other work while I/O happens
-```
-
-### When Async Doesn't Help
-
-Async doesn't improve performance for:
-- **CPU-bound operations** (already fast)
-- **Local SSD I/O** (I/O is fast enough)
-- **Single-threaded scenarios** (no parallelism benefit)
-
-```csharp
-// Sync extraction (simpler, same performance on fast I/O)
-using (var archive = ZipArchive.Open("archive.zip"))
-{
-    archive.WriteToDirectory(
-        @"C:\output",
-        new ExtractionOptions { ExtractFullPath = true, Overwrite = true }
-    );
-}
-// Simple and fast - no async needed
-```
-
-### Cancellation Pattern
-
-```csharp
-var cts = new CancellationTokenSource();
-
-// Cancel after 5 minutes
-cts.CancelAfter(TimeSpan.FromMinutes(5));
-
-try
-{
-    using (var archive = ZipArchive.Open("archive.zip"))
-    {
-        await archive.WriteToDirectoryAsync(
-            @"C:\output",
-            new ExtractionOptions { ExtractFullPath = true, Overwrite = true },
-            cts.Token
-        );
-    }
-}
-catch (OperationCanceledException)
-{
-    Console.WriteLine("Extraction cancelled");
-    // Clean up partial extraction if needed
-}
-```
-
----
-
-## Practical Performance Tips
-
-### 1. Choose the Right API
-
-| Scenario | API | Why |
-|----------|-----|-----|
-| Small archives | Archive | Faster random access |
-| Large archives | Reader | Lower memory |
-| Streaming | Reader | Works on non-seekable streams |
-| Download streams | Reader | Async extraction while downloading |
-
-### 2. Batch Operations
-
-```csharp
-// ✗ Slow - opens each archive separately
-foreach (var file in files)
-{
-    using (var archive = ZipArchive.Open("archive.zip"))
-    {
-        archive.WriteToDirectory(@"C:\output");
-    }
-}
-
-// ✓ Better - process multiple entries at once
-using (var archive = ZipArchive.Open("archive.zip"))
-{
-    archive.WriteToDirectory(@"C:\output");
-}
-```
-
-### 3. Profile Your Code
-
-```csharp
-var sw = Stopwatch.StartNew();
-using (var archive = ZipArchive.Open("large.zip"))
-{
-    archive.WriteToDirectory(@"C:\output");
-}
-sw.Stop();
-
-Console.WriteLine($"Extraction took {sw.ElapsedMilliseconds}ms");
-
-// Measure memory before/after
-var beforeMem = GC.GetTotalMemory(true);
-// ... do work ...
-var afterMem = GC.GetTotalMemory(true);
-Console.WriteLine($"Memory used: {(afterMem - beforeMem) / 1024 / 1024}MB");
-```
-

-
-## Troubleshooting Performance
-
-### Extraction is Slow
-
-1. **Check if solid archive** → Use sequential extraction
-2. **Check API** → Reader API might be faster for large files
-3. **Check compression level** → Higher levels are slower to decompress
-4. **Check I/O** → Network drives are much slower than SSD
-5. **Check buffer size** → May need larger buffers for network
-
-### High Memory Usage
-
-1. **Use Reader API** instead of Archive API
-2. **Process entries immediately** rather than buffering
-3. **Reduce compression level** if writing
-4. **Check for memory leaks** in your code
-
-### CPU Usage at 100%
-
-1. **Normal for compression** - especially with high compression levels
-2. **Consider lower level** for faster processing
-3. **Reduce parallelism** if processing multiple archives
-4. **Check if awaiting properly** in async code

-# SharpCompress Usage
-
-## Async/Await Support (Beta)
-
-SharpCompress now provides full async/await support for all I/O operations. All `Read`, `Write`, and extraction operations have async equivalents ending in `Async` that accept an optional `CancellationToken`. This enables better performance and scalability for I/O-bound operations.
-
-**Key Async Methods:**
-- `reader.WriteEntryToAsync(stream, cancellationToken)` - Extract entry asynchronously  
-- `reader.WriteAllToDirectoryAsync(path, options, cancellationToken)` - Extract all asynchronously
-- `writer.WriteAsync(filename, stream, modTime, cancellationToken)` - Write entry asynchronously
-- `writer.WriteAllAsync(directory, pattern, searchOption, cancellationToken)` - Write directory asynchronously
-- `entry.OpenEntryStreamAsync(cancellationToken)` - Open entry stream asynchronously
-
-See [Async Examples](#async-examples) section below for usage patterns.
-
-## Stream Rules
-
-When dealing with Streams, the rule should be that you don't close a stream you didn't create. This, in effect, should mean you should always put a Stream in a using block to dispose it. 
-
-However, the .NET Framework often has classes that will dispose streams by default to make things "easy" like the following:
-
-```C#
-using (var reader = new StreamReader(File.Open("foo")))
-{
-    ...
-}
-```
-
-In this example, reader should get disposed. However, stream rules should say the the `FileStream` created by `File.Open` should remain open. However, the .NET Framework closes it for you by default unless you override the constructor. In general, you should be writing Stream code like this:
-
-```C#
-using (var fileStream = File.Open("foo"))
-using (var reader = new StreamReader(fileStream))
-{
-    ...
-}
-```
-
-To deal with the "correct" rules as well as the expectations of users, I've decided to always close wrapped streams as of 0.21.
-
-To be explicit though, consider always using the overloads that use `ReaderOptions` or `WriterOptions` and explicitly set `LeaveStreamOpen` the way you want.
-
-If using Compression Stream classes directly and you don't want the wrapped stream to be closed.  Use the `NonDisposingStream` as a wrapper to prevent the stream being disposed.  The change in 0.21 simplified a lot even though the usage is a bit more convoluted.
-
-## Samples
-
-Also, look over the tests for more thorough [examples](https://github.com/adamhathcock/sharpcompress/tree/master/tests/SharpCompress.Test)
-
-### Create Zip Archive from multiple files
-```C#
-using(var archive = ZipArchive.Create())
-{
-    archive.AddEntry("file01.txt", "C:\\file01.txt");
-    archive.AddEntry("file02.txt", "C:\\file02.txt");
-    ...
-    
-    archive.SaveTo("C:\\temp.zip", CompressionType.Deflate);
-}
-```
-
-### Create Zip Archive from all files in a directory to a file
-
-```C#
-using (var archive = ZipArchive.Create())
-{
-    archive.AddAllFromDirectory("D:\\temp");
-    archive.SaveTo("C:\\temp.zip", CompressionType.Deflate);
-}
-```
-
-### Create Zip Archive from all files in a directory and save in memory
-
-```C#
-var memoryStream = new MemoryStream();
-using (var archive = ZipArchive.Create())
-{
-    archive.AddAllFromDirectory("D:\\temp");
-    archive.SaveTo(memoryStream, new WriterOptions(CompressionType.Deflate)
-                                {
-                                    LeaveStreamOpen = true
-                                });
-}
-//reset memoryStream to be usable now
-memoryStream.Position = 0;
-```
-
-### Extract all files from a rar file to a directory using RarArchive
-
-Note: Extracting a solid rar or 7z file needs to be done in sequential order to get acceptable decompression speed.
-`ExtractAllEntries` is primarily intended for solid archives (like solid Rar) or 7Zip archives, where sequential extraction provides the best performance. For general/simple extraction with any supported archive type, use `archive.WriteToDirectory()` instead.
-
-```C#
-using (var archive = RarArchive.Open("Test.rar"))
-{
-    // Simple extraction with RarArchive; this WriteToDirectory pattern works for all archive types
-    archive.WriteToDirectory(@"D:\temp", new ExtractionOptions()
-    {
-        ExtractFullPath = true,
-        Overwrite = true
-    });
-}
-```
-
-### Iterate over all files from a Rar file using RarArchive
-
-```C#
-using (var archive = RarArchive.Open("Test.rar"))
-{
-    foreach (var entry in archive.Entries.Where(entry => !entry.IsDirectory))
-    {
-        Console.WriteLine($"{entry.Key}: {entry.Size} bytes");
-    }
-}
-```
-
-### Extract solid Rar or 7Zip archives with progress reporting
-
-`ExtractAllEntries` only works for solid archives (Rar) or 7Zip archives. For optimal performance with these archive types, use this method:
-
-```C#
-using SharpCompress.Common;
-using SharpCompress.Readers;
-
-var progress = new Progress<ProgressReport>(report =>
-{
-    Console.WriteLine($"Extracting {report.EntryPath}: {report.PercentComplete}%");
-});
-
-using (var archive = RarArchive.Open("archive.rar", new ReaderOptions { Progress = progress })) // Must be solid Rar or 7Zip
-{
-    archive.WriteToDirectory(@"D:\output", new ExtractionOptions()
-    {
-        ExtractFullPath = true,
-        Overwrite = true
-    });
-}
-```
-
-### Use ReaderFactory to autodetect archive type and Open the entry stream
-
-```C#
-using (Stream stream = File.OpenRead("Tar.tar.bz2"))
-using (var reader = ReaderFactory.Open(stream))
-{
-    while (reader.MoveToNextEntry())
-    {
-        if (!reader.Entry.IsDirectory)
-        {
-            Console.WriteLine(reader.Entry.Key);
-            reader.WriteEntryToDirectory(@"C:\temp", new ExtractionOptions()
-            {
-                ExtractFullPath = true,
-                Overwrite = true
-            });
-        }
-    }
-}
-```
-
-### Use ReaderFactory to autodetect archive type and Open the entry stream
-
-```C#
-using (Stream stream = File.OpenRead("Tar.tar.bz2"))
-using (var reader = ReaderFactory.Open(stream))
-{
-    while (reader.MoveToNextEntry())
-    {
-        if (!reader.Entry.IsDirectory)
-        {
-            using (var entryStream = reader.OpenEntryStream())
-            {
-                entryStream.CopyTo(...);
-            }
-        }
-    }
-}
-```
-
-### Use WriterFactory to write all files from a directory in a streaming manner.
-
-```C#
-using (Stream stream = File.OpenWrite("C:\\temp.tgz"))
-using (var writer = WriterFactory.Open(stream, ArchiveType.Tar, new WriterOptions(CompressionType.GZip)
-                                                {
-                                                    LeaveOpenStream = true
-                                                }))
-{
-    writer.WriteAll("D:\\temp", "*", SearchOption.AllDirectories);
-}
-```
-
-### Extract zip which has non-utf8 encoded filename(cp932)
-
-```C#
-var opts = new SharpCompress.Readers.ReaderOptions();
-var encoding = Encoding.GetEncoding(932);
-opts.ArchiveEncoding = new SharpCompress.Common.ArchiveEncoding();
-opts.ArchiveEncoding.CustomDecoder = (data, x, y) =>
-{
-    return encoding.GetString(data);
-};
-var tr = SharpCompress.Archives.Zip.ZipArchive.Open("test.zip", opts);
-foreach(var entry in tr.Entries)
-{
-    Console.WriteLine($"{entry.Key}");
-}
-```
-
-## Async Examples
-
-### Async Reader Examples
-
-**Extract single entry asynchronously:**

-    {
-        using (var entryStream = await entry.OpenEntryStreamAsync(cancellationToken))
-        {
-            // Process the decompressed stream asynchronously
-            await ProcessStreamAsync(entryStream, cancellationToken);
-        }
-    }
-}
-```
-
-### Async Writer Examples

-using (var writer = WriterFactory.Open(archiveStream, ArchiveType.Zip, CompressionType.Deflate))
-{
-    using (Stream fileStream = File.OpenRead("input.txt"))
-    {
-        await writer.WriteAsync("entry.txt", fileStream, DateTime.Now, cancellationToken);
-    }
-}
-```
-
-**Write entire directory asynchronously:**
-```C#
-using (Stream stream = File.OpenWrite("backup.tar.gz"))
-using (var writer = WriterFactory.Open(stream, ArchiveType.Tar, new WriterOptions(CompressionType.GZip)))
-{
-    await writer.WriteAllAsync(
-        @"D:\files",
-        "*",
-        SearchOption.AllDirectories,
-        cancellationToken
-    );
-}
-```
-
-**Write with progress tracking and cancellation:**
-```C#
-var cts = new CancellationTokenSource();
-
-// Set timeout or cancel from UI
-cts.CancelAfter(TimeSpan.FromMinutes(5));
-
-using (Stream stream = File.OpenWrite("archive.zip"))
-using (var writer = WriterFactory.Open(stream, ArchiveType.Zip, CompressionType.Deflate))
-{
-    try
-    {
-        await writer.WriteAllAsync(@"D:\data", "*", SearchOption.AllDirectories, cts.Token);

-
-* We used "Screaming Fast Galois Field Arithmetic Using Intel
-  SIMD Instructions" paper by James S. Plank, Kevin M. Greenan
-  and Ethan L. Miller to improve Reed-Solomon coding performance.
-  Also we are grateful to Artem Drobanov and Bulat Ziganshin
-  for samples and ideas allowed to make Reed-Solomon coding
-  more efficient.
-
-* RAR text compression algorithm is based on Dmitry Shkarin PPMII
-  and Dmitry Subbotin carryless rangecoder public domain source code.
-  You may find it in ftp.elf.stuba.sk/pub/pc/pack.
-
-* RAR encryption includes parts of code from Szymon Stefanek
-  and Brian Gladman AES implementations also as Steve Reid SHA-1 source.
