About SII files
The .sii file extension is primarily a game data definition file and save game file used by SCS Software truck simulators, most notably Euro Truck Simulator 2 and American Truck Simulator. These files store everything from engine physics and mod configurations to player progress and economy data. While some .sii files inside mod archives are stored as plain text, official save files are usually encrypted or compiled into a binary format (often labeled ScsB) to prevent cheating and save disk space. This proprietary encryption is a major disadvantage for players: it means you cannot open the files directly in Notepad or Visual Studio Code - all you will see is garbled, unreadable text. To edit your save game, add money, or modify truck parts, you must bypass this format. For quick modding or text editing, convert .sii to TXT. If you are building automated modding tools, convert to JSON or XML to maintain data structure.
Convert.Guru analyzes your SII file, detects the exact format, and lets you read the text inside.
If you want to convert SII file to EXE, ISO, BIN, CUE, PAK, WAD, PK3, PK4, BSP, MAP, SAV or DAT, you can use Euro Truck Simulator 2 or similar software from the "Game Save and Configuration" category. In the File menu, look for Save As… or Export….
To convert MOD, BIN, CFG, SCX, DAT, MPQ, LOG, CUE, INI, EXE, SCM or ISO files to SII, try Euro Truck Simulator 2 or another comparable tool in the "Game Save and Configuration" category.
The SII Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SII converter.
