  • Quake III Engine PAK File by Id Software, Inc.Renamed .ZIP file. It is strongly recommended that .PK3 files installed with commercial games not be modified or extracted and re-compressed. All known Quake III Engine games check the exact size (and maybe other feathers) of a .PAK file before using it and any modification would irreversibly corrupt the file; the file would still be viewable, but the game's executable would no longer recognize it. However, if viewed with a hands-off aproach one should find music, textures, text and the like easily extracted and viewed without harm to the functionality of the games that require them. The identifying characters used for this association are - Hex: 50 4B 03 04 , ASCII: PK Related links: Dragon UnPACKer
