What is an OF file?

OF files mostly belong to Steam. OF files can serve different roles in the gaming world.
When used as a Windows executable, an OF file follows the standard EXE structure and is part of a proprietary object format. This type is associated with Valve’s system and can be seen in files that work with Valve Pak packages. For more details on this usage, visit the Steam page.
In other cases, an OF file holds 3D model outfit information. These files store data for character clothing and accessories and are typically opened with tools like Outfit Studio or similar editors.
There are also OF files that serve as game data files, holding configuration or asset information for games such as Open Fortress. More on this can be found at the Open Fortress website.
Usage Tips:
  • Always verify the file source before opening.
  • Use the proper tool that corresponds to the file’s data type.
  • If the file is executable, avoid running it without confirming its origin.
  • Backup the file before making any changes.
  • FilExt.com tip: Each variant of the OF file requires the appropriate software to view or edit its contents.
