What is a SCO file?
A .SCO file is a multi-purpose data file primarily used in video games and simulation software. Because many developers use the .SCO extension, the exact format depends on the creator software. Commonly, a .SCO file is a game scene definition file for Mount & Blade or a compiled script file for games built on the Rockstar Advanced Game Engine, such as Grand Theft Auto V.
Other Common Uses
The .SCO extension also functions as a 3D model format in League of Legends, often edited using 3ds Max. In simulation software, it is widely known as an OMSI Scenery Object Configuration File created by MR Software for the OMSI Bus Simulator. Other rare uses include digital sheet music scores for Avid Sibelius Scorch, TotalRecovery backup images, and CAD data files.
How to open SCO files?
Opening a .SCO file requires knowing its specific origin. Mount & Blade scene files are modified using the game's official editor. Rockstar script files require specialized community tools like ScriptHookV for modding. OMSI Scenery Object files are often plain text and can be edited with the OMSI Object Editing Tool or a standard text editor.
Best practices and troubleshooting
Because .SCO files have multiple possible meanings, guessing the correct software can be frustrating. Opening a compiled script in a text editor will show unreadable characters, while trying to load a CAD file into a game engine will cause an error. We recommend analyzing the file structure first to determine its true origin.
