This little tool, made for modders, is an automatic file extraction software for games based on the IdTech4 engine (also known as Trinity) developed and owned by id Software. The supported games are: Doom 3, Doom 3 Resurrection of Evil, Quake 4, Prey and Enemy Territory: Quake Wars (Wolfenstein and Brink are not supported at the moment). IdTech4 File Unpacker is useful to extract the entire game data preserving the correct files and folders structure from all the pk4s archives used by the game and by subsequent patches. This new version is compatible with 32bit and 64bit Windows Operating Systems; it features the DotNetZip library for faster and safer extraction; a new multi-threading core; new buttons to explore the supported games installation folders and many other minor tweaks.
