This software is an open source Zip framework written in Objective-C for Mac OS X. It allows for efficient compression and decompression of files and is available for free use.
One of the standout features of ZipKit is its compatibility with resource forks in a way that's fully compatible with Mac OS X's Archive Utility. This means you won't have to worry about any compatibility issues or broken files when working with Zip archives on your Mac.
Another great feature of ZipKit is its ability to provide a clean interruption for archiving. This means you can easily cancel archiving operations from the invoking object, be it a NSThread or NSOperation. This level of control and flexibility makes working with Zip archives a breeze.
Overall, ZipKit is an impressive framework that developers should strongly consider adding to their toolkit. With its support for standard Zip formats, large file sizes, resource forks, and clean interruption, it's hard to find a better solution for working with Zip archives on Mac OS X.
