Small app to extract files from (mostly) game archive formats. Currently supports Neverwinter Nights, Homeworld 2, BloodRayne, WC IV, Drakensang, InstallKit, MGS TS, WAD, LFD and Bard’s Tale.
It also has a “generic” module to find RIFF, BMP, PNG and other files in any uncompressed archives. That mode might however find things that are not there, or produce broken files after extracting.
