FXD to CG4 Conversion: FAQ

What are FXD files?

The FXD image format is associated with WinFax, a popular program in the 1990s for sending and receiving fax messages using a Windows-based computer and a separate fax machine. The software facilitated the connection of the two devices and could store both sent and received documents. An FXD file contains the image of a sent fax document. WinFax was first released in 1990 by Delrina, later on acquired by Symantec. The format is currently considered archaic and obsolete.
