QuaZIP is a simple C++ wrapper over Gilles Vollant's ZIP/UNZIP package that can be used to access ZIP archives. It uses Trolltech's Qt toolkit. QuaZIP allows you to access files inside ZIP archives using QIODevice API, and - yes! - that means that you can also use QTextStream, QDataStream or whatever you would like to use on your zipped files. QuaZIP provides complete abstraction of the ZIP/UNZIP API, for both reading from and writing to ZIP archives.
