 # Archive Formats
 
 ## Accessing Archives

 Archive classes allow random access to a seekable stream.
 Reader classes allow forward-only reading
 Writer classes allow forward-only Writing

  1. SOLID Rars are only supported in the RarReader API.
- 2. Zip format supports pkware and WinzipAES encryption.  However, encrypted LZMA is not supported.
+ 2. Zip format supports pkware and WinzipAES encryption.  However, encrypted LZMA is not supported.  Zip64 reading is supported.
  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
