What is a GF file

GF files mostly belong to Sonic Foundry. GF files are used in two main ways. One format is a game file used as a secure container for game data. In this case, the file stores data used by a game engine or secure folder system. You may find references to this use on the Sonic Foundry site.
The other format is a graphics file that holds gradient information. This type is used by Adobe programs such as ImageReady and Photoshop to manage color transitions in designs.

Game File: Holds secure game data for internal use.

Graphics File: Contains gradient settings for image editing.

Why is it important to know the file format? This is the only way to find out which program to use to open the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ.

• 10% of all GF files are using the well-known JFIF file format to store the data. JFIF is short for JPEG File Interchange Format. It is a bitmap graphic that uses JPEG compression.
