PK3 to IFF Conversion: FAQ

What are PK3 files?

The PK3 format is associated with several video games created with the Quake 3 Arena game software framework (also known as id Tech 3). PK3 files are in fact renamed ZIP archive files that contain several types of game data, defining maps, models, sounds, textures or weapons, among others.
