File used by Simutrans, a free transportation simulation game; contains game object graphics and properties; compiled from a plain text ".dat" data file and a source .PNG image; used for game vehicles, buildings, terrain, and other objects.
To modify Simutrans objects, users typically don't edit the PAK files directly. Instead, they usually download the source DAT and PNG files used to package a PAK file, modify the files, and then re-pack the contents into a new PAK file. PAK files are built using the MakeObj.exe program.
NOTE: PakBuilder is a GUI program used to create PAK files. It cannot open them.
Game archive used by video games such as Quake, Hexen, and Half-Life; may include graphics, objects, textures, sounds, and other game data "packed" into a single file; can be browsed or viewed with several applications.
NOTE: The format for a PAK file used by one game may differ from the PAK format used for a different game. Therefore, you may have to try multiple programs before opening your PAK file.
