What is a G3F file

G3F files mostly belong to Fax Viewer. G3F files can serve two distinct roles.
Fax document (Group 3 format):
  • This file holds fax data encoded with the Group 3 standard.
  • It compresses black and white images for transmission in fax systems.
  • Programs like Fax Viewer and tools from GFI FaxMaker open these files.
    • 3D geoscience data:
  • This file may store 3D geoscience data used in geological surveys.
  • Software such as Geosoft Oasis montaj processes these data sets. For more details, visit the Geosoft Oasis montaj page.
  • In some cases, these files are also used as preset files for GUITAR RIG 5.

    • How do you open G3F files?

    You need a suitable software like Fax Viewer to open a G3F file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your G3F file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a G3F file directly in the browser:. Just drag the file onto this browser window and drop it.
