JMPQ3

Note: Since Version 1.9.0 jmpq3 requires Java 11 or higher

What?

JMPQ3 is a small java library for accessing and modifying mpq (MoPaQ) archives. Common file endings are .mpq, .w3m, .w3x.

MoPaQ is Blizzard's old, proprietary archive format for storing gamedata (replaced with CASC).

You can find more info and an excellent graphical editor here http://www.zezula.net/en/mpq/main.html

Known issues:

• Unsupported decompression algorithms: sparse and bzip2
• Only supported compression is zlib/zopfli
• JMPQ doesn't build a valid (attributes) file for now. (which seems to be fine for warcraft3)
