• SSF - Saturn (under development)
• DSF - Dreamcast (under development)
• USF - Nintendo 64 (developed by Adam Gashlin)

Support file used by GPS software; contains the root mean square (RMS) values of ephemeris components, which define the positions of celestial objects; also includes the clock time for each tracked satellite over the past seven days.

Prediction support files are used to determine how individual satellites are performing. They can also be used to calculate statistical estimates of long term GPS accuracy.

Bitmap image format used by PhotoStudio, an image-editing program; supports text, shapes, and multiple layers; commonly used for saving edited digital photos.

ArcSoft PhotoStudio for Canon is commonly included with Canon digital cameras.
