.USF File Extension

Skin file used by EVGA Precision X, a program used for overclocking GPUs; stores graphics and layout information that alter the appearance of the application's GUI; allows users to customize the look and feel of the interface.

Music format used by Nintendo 64 (N64) games; stores the soundtrack of N64 video games; may also contain an SR64 ROM image and recent save state.

USF files are often saved in sets that include several .MINIUSF files and a single .USFLIB file.

Video subtitles file created in the Universal Subtitle Format (USF); uses XML text formatting instead of plain text used by many other subtitle formats; used for synchronizing textual and image subtitles with a movie; supported by some video playback programs.

USF was designed to be a universal format that incorporated the best of all subtitling formats into a flexible and portable format. However, it was not widely adopted, perhaps because of the verbosity of the XML syntax.
