Description
The FXS file format is associated with WinFax, a software application designed for sending, receiving, and managing faxes directly from a computer. Developed by Symantec, WinFax uses the FXS file type primarily for storing fax documents in a proprietary format. These files contain the digital representation of a fax message, including text and images, allowing for electronic management of faxes without the need for a physical fax machine. The FXS format is specifically designed to be used within the WinFax software for viewing, editing, or forwarding fax documents.
