Notes about the IFX 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 IFX file type is primarily associated with 'Fax File'. Some programs may use .IFX for a fax. These are usually TIFF files and can often be opened in an image editor like Paint.
