Notes about the G3F file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The G3F file type is primarily associated with 'Zetafax' by Equisys. Zetafax uses the TIFF file format for storing faxes. It uses the extensions .G3F and .G3N for fine and normal resolution TIFF files respectively.
