- This unzip package allow extract file from .ZIP file, compatible with PKZip 2.04g
- WinZip, InfoZip tools and compatible.
+ Modifications of Unzip for Zip64
+ Copyright (C) 2007-2008 Even Rouault
- Multi volume ZipFile (span) are not supported.
- Encryption compatible with pkzip 2.04g only supported
- Old compressions used by old PKZip 1.x are not supported
+ Modifications for Zip64 support on both zip and unzip
