The mpq-tools software allows for the manipulation of mpq archives effectively.
But that's not all. If you're a developer looking to work with mpq archives, then you're in luck. Since version 0.4.0, mpq-tools includes a full API documentation that's sure to come in handy.
For those who may not be aware, MPQ or MoPaQ, is a proprietary archive format that was created by Mike O'Brien in 1996 for use with Diablo. The archive format has since been used by many Blizzard titles such as Diablo, Diablo 2, Starcraft, Warcraft 2: BNE, and even a newer version in Warcraft 3. However, the copyrights to it are held by Havas Interactive, Blizzard's parent company.
If you're ready to give mpq-tools a try, the installation process is fairly simple. Just download the mpq-tools-0.x.x.tar.gz file, extract it, and run the configure, make, and make install commands. With its user-friendly interface and helpful features, mpq-tools is definitely worth checking out.
