File Extension List

New programs are constantly being created and it is important for our computer to be able to tell what kind of file it is accessing. By viewing a files extension, our pc recognizes precisely how to access that file.

The data needed to select which program to use to access a file is taken from the files extension. A files extension carries hints to the formatting of the file and what sort of data it contains. Some of the more general file extensions include .exe for executables, .wav for sound, and .doc for documents. You may already be familiar with these common extensions but with the always developing library of programs and operating systems there are much more that you may have never discovered.
