AS3 Zip Library is a tool for reading and writing zip files.It does not require a script to preprocess a zip and inject Addler32 checksums, because it implements a deflate compression decoder (inflater). Some of the features:
- Read or write zip files
- Interface based on Java API (java.util.zip package)
I recommend using FZip ( http://codeazur.com.br/lab/fzip/ ) which is 2 times faster
Thanks for the tip, Nicolas!
