ZipArchive Library is a free library that adds zip compression and decompression functionality to your program, allowing you to create and modify ZIP files in the compatible way with WinZip, PKZIP and other popular archivers. Its easy and practical interface makes the library suitable for the beginners as well as for the advanced users.

Here are some key features of "ZipArchive Library":

· 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
· optimized replacing and renaming files in the archive
· compression from and decompression to memory, create the whole archive in memory, extract the archive from memory (see Creating and extracting archives from/in memory)
· password encryption and decryption supported
· possibility to create or extract self-extracting archives
· smart compression, if enabled, prevents the file in the archive to be larger after compression (see CZipArchive::Smartness)
· safe compression with CZipArchive::Flush function
· using callback objects for notifications
· to provide easy disk change in a multi-disk archives
· for the progress control when adding, extracting, testing or deleting files or saving archive's central directory

· possibility to integrate help system with MSDN (see Integrating with MSDN (Visual Studio 6.0 only))
· easy interface
· easy transfer to other system platforms
· speedy
· well documented
· full source code provided
· Visual Studio Projects: version 2005 (available with the library), versions 6.0 and 2003 (available at download page .)
· sample applications provided (for the STL version located in stl/zippie, the MFC version (multithreaded) is available separately
