- work in a compatible way with PKZIP and WinZip
- create, modify, extract and test zip archives
- create and extract multi-disk archives (on non-removable disks as well)
- add file to the archive from another archive without decompressing the file (copy compressed data) (see CZipArchive::GetFromArchive)
- highly optimized deleting multiple files from the archive
