SCS Software Game Data

SCS Software is a video game developer known primarily for publishing the Truck Simulator series, which includes Euro Truck Simulator, UK Truck Simulator, and American Truck Simulator. All of SCS Software's truck-related video games use SII files, which store various game data.

Some SII files, such as controls.sii , contain plain text data. Players can open and edit these files in any text editor to customize the related game. Other SII files, such as profile.sii , are saved as binary files by default.

However, players can choose to save some binary SII files as encrypted plain text files, to make them editable. For example, if a player sets Euro Truck Simulator 2's g_save_format configuration parameter (found in the game's config.cfg file) to 2 , the game will begin saving game.sii , which contains a player's saved game data, as an encrypted plain text file instead of a binary file. The player can then use the third-party SII_DECRYPT utility to decrypt game.sii , turning it into a normal plain text file (which can be opened and edited in any text editor).

If your SII file contains plain text data, you can open it with Microsoft Notepad , Apple TextEdit , or any other text editor, to view and edit the data it contains. If the plain text data your SII file contains is encrypted , you may first have to decrypt it with SII_DECRYPT.

If your SII file contains binary data, it is not meant to be opened or edited.
