Originally created by @aaasoft on GitHub (Nov 14, 2025).

Recently,I update SharpComporess from 0.40.0 to 0.41.0 in my project.
I found ZipArchive.ExtractToDirectory method not work.
No file extracted and no exception throwed,nothing happen.

Test Zip file: https://builds.dotnet.microsoft.com/dotnet/aspnetcore/Runtime/10.0.0/aspnetcore-runtime-10.0.0-win-x64.zip
Test code:

using (var archive = SharpCompress.Archives.Zip.ZipArchive.Open("aspnetcore-runtime-10.0.0-win-x64.zip")) archive.ExtractToDirectory("Test");

Works for me. This example will always put a Test directory in your build output

@adamhathcock You tested on mac os,but I tested on Windows 10,the bug is still there.

I add some output and a stopwatch,here is my last test code:

using SharpCompress.Archives;
using SharpCompress.Archives.Zip;
using System.Diagnostics;
using System.Runtime.InteropServices;

var zipFile = "aspnetcore-runtime-10.0.0-win-x64.zip";
var folder = "Test";

//Print info
Console.WriteLine("SharpCompress version: " + typeof(ZipArchive).Assembly.GetName().Version);
Console.WriteLine("OS: " + RuntimeInformation.OSDescription);
Console.WriteLine("Framework: " + RuntimeInformation.FrameworkDescription);
Console.WriteLine("-------------");

//Cleanup
if (Directory.Exists(folder))
    Directory.Delete(folder, true);

//Decompress
Console.WriteLine($"Begin decompress....");
var stopwatch = new Stopwatch();
stopwatch.Start();
using (var archive = ZipArchive.Open(zipFile))
    archive.ExtractToDirectory(folder);
stopwatch.Stop();
Console.WriteLine($"Decompress done,used time: {stopwatch.Elapsed}");

//Check if folder exists
Console.WriteLine($"Folder exists: {Directory.Exists(folder)}");

Version 0.40.0 test result:

SharpCompress version: 0.40.0.0
OS: Microsoft Windows 10.0.19045
Framework: .NET 8.0.22
-------------

Folder exists: True

Version 0.41.0 test result:

The underlying cause for this issue is the same as in #960.

@adamhathcock @Morilli ZIP file is not SOLID.I think IArchive.ExtractToDirectory method should work with any archive files,not just SOLID archives.

Is this commit cause this bug?
make WriteToDirectory functions use ExtractAllEntries
