This file extension is also used by Soldier of Fortune 2, Jedi Knight and other 3D action games. These PK3 files may contain textures, audio clips, custom maps and other types of data used to modify the game play. The files using the PK3 file extension may be compared to the PAK game data files.

The PK3 files may be viewed or extracted with the use of a file archiver that supports the ZIP file format. The files of this kind may also be created using a software application intended for that purpose.
