Zip Package is a set of classes for reading and writing .zip files on Mac OS X, Windows and Linux.
If you create Zip archives using Zip Package, any Zip compatible software working on any operating system will be able to unpack them.
Here are some key features of "Zip Package":
· New in version 2: Does not require a plugin any more (but can still use the Einhugur e-CryptIt plugin for slightly better performance), using instead the free zlib library, which is even already pre-installed on OS X and Linux systems (you'll have to bundle it on Windows yourself, though).
· Compress entire folders with just a few calls.
· Make incremental backups of folder trees, updating only changed files while keeping multiple snapshots of your folder structure.
· MacBinary support (for preserving Mac OS X's resource forks, particularly Alias files).
· Compatible with PKZIP, Info-Zip, Aladdin Stuffit Zip, ZipIt, WinZip, etc.
· Open source, i.e. you get the complete source code.
Requirements:
· REALbasic
