ZipArchive Library 4.0.0

ZipArchive Library 4.0.0 is designed to provide you with a great library for C++ programmers.

This library adds zip compression and decompression functionality to your software, allowing you to create and modify ZIP files in the compatible way with WinZip, PKZIP and other popular zip archivers. The library supports all possible operations on a zip archive: creating, extracting, adding, renaming, deleting files from the archive, modifications of an existing archive.

There is also the support for the Zip64 format (large files and archives), AES encryption and decryption compatible with the WinZip format, standard zip encryption and decryption, Unicode support for filenames and comments (WinZip compatible), bzip2 compression algorithm, creating and extracting multiple disk archives (splitting and spanning), creating and extracting archives in/from memory.

It's easy and practical interface makes the library suitable for the beginners as well as for the advanced users. Full source code and comprehensive documentation are provided. Free for non-commercial use and under some conditions for commercial use as well. The Zip64, AES, Unicode and the bzip2 functionality are available in the commercial version only (trial version of the full functionality is available from the authors web site).
