This file is saved in a binary format, which requires a specific program to read its contents.

Definition

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.

More Information

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.
