What is an HFX file?

HFX files mostly belong to WinFax Pro. Fax Documents via TIFF: HFX files are often used to store fax documents. They usually carry a TIFF structure that many fax systems use. For example, HFMC uses these files with applications like WinFax Pro to send and receive fax images.
ProShow Slideshow Files: At times, the same HFX extension marks files that hold data for photo slideshows. These files work with software such as ProShow Gold and are used to produce photo slideshow effects.
Multimedia and Graphics Data: In other cases, HFX files use the RIFF format to store graphics or even proprietary multimedia information, sometimes shown as a Halifax NSA321/322 Disk Image. This usage shows a different internal data structure within the same file extension.
Key Detail: The reuse of the HFX extension for distinct internal formats makes it important to check the file’s properties to decide the correct application for opening and viewing it.

Use fax software for TIFF-based fax documents.
Open slideshow files with ProShow Gold if they contain photo effects.
If the file uses RIFF, inspect it with a hex editor or check for multimedia support.
