What is the .FXD File Extension?

.FXD File Extension Description:

The file extension .fxd finds association in two kinds of faxing applications, and also as a component of one programming language. To understand how the .fxd file extension functions as a component of fax software, it is necessary to get a grasp of how the program operates. Basically, fax software applies the same methodology as a conventional fax, except that the computer system acts as the fax machine, and paper documentation is optional. The computer would need a device called a fax modem in order to simulate the features inherent in a typical fax machine.

The fax application is incorporated usually with the default word processing application, to allow the user to directly send the document after typing it. The system can also receive fax documents with the fax modem acting as a decoder of the coded electronic image, and saving it as a fax file. If a user needs a paper copy of the received fax-like documents with the .fxd file extension, he can send the fax document to a printer to get the hard copy.

Under the FaxIt application, the file extension .fxd plays the role of a phonebook card file, similar to a phone directory that contains the name and fax number (even other relevant information like company, address, etc.) of an intended recipient, which is retrieved by the application prior to sending of the fax document. A recipient not included in the .fxd file extension phonebook would require the sender to manually key in the fax number. The application may also ask the sender if he would like to add the entry to the phonebook file, so the next time the file extension .fxd is accessed, it is included in the phonebook.

An important aspect of the faxing procedure is that the fax software must be able to recognize and communicate with the fax modem device installed in the computer. It must be understood that fax software is different from a fax service usually offered on the Internet, because the fax software talks to the fax modem, and the device uses the conventional telephone line to transmit the fax document.

The WinFax application also uses the .fxd file extension relative to its faxing operation with some distinct differences. First, under the WinFax program, the file extension .fxd is affixed to fax documents, which were successfully sent in order to differentiate them from those that are queued for sending. Second, the FaxIt application only sends fax documents but does not receive them, unlike the WinFax application, which can handle both.

The file extension .fxd is also associated with the FoxPro programming language, and is used mainly in the documentation process of the application. Code documentors are used in programming applications to create a technical documentation of the software. However, not all programming languages have a built-in documentation generator. For the FoxPro application, the FoxDoc, by using the .fxd file extension, effectively shows how the program was created, which differentiates it from user documentation and system documentation.
