What is a PAK file?
A PAK file is an archive used by video games such as Quake, Hexen, Crysis, Far Cry, and Half-Life. It may include graphics, objects, textures, sounds, and other game data "packed" into a single file. PAK files are often just a renamed .ZIP file.
PAK files are primarily used by video games but may also be used by other applications such as the Google Chrome web browser. 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.

.PAK File Association 3
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.
