What is an G3F file?

The .G3F file extension is associated with Zetafax, a fax server software developed by Equisys. These files are used to store fax images in a digital format, allowing for electronic transmission and archiving of fax documents.

More Information.

Zetafax was introduced in the early 1990s as a solution for businesses to manage their fax communications digitally. The .G3F format was created to store the images of faxes received or sent through the Zetafax system, providing a digital equivalent to traditional fax paper documents. Its purpose was to reduce the reliance on physical fax machines and streamline fax communication.

Origin Of This File.

The .G3F file format originated from Zetafax, a product designed to facilitate the sending and receiving of faxes via computer networks. The format is designed to encapsulate fax image data efficiently, optimizing it for quick transmission and reliable storage.

File Structure Technical Specification.

The .G3F file format is a type of Group 3 fax image format, which follows the ITU-T T.4 standard for encoding monochrome images.

The structure of a .G3F file includes:

Header: Contains metadata such as file type, version, and image dimensions.
Image Data: Encoded using Group 3 compression, which is a form of run-length encoding optimized for fax transmission.
