File Extension List

New software is constantly being produced and it is essential for our system to know how to tell what kind of file it is accessing. By examining a files extension, our system knows exactly how to make use of that file.

To find out which application to open a file with, your computer first gathers the necessary data from the files extension. Information about the format and type of information contained inside a file is designated by the file extension. A few of the more general file extensions include .exe for executables, .wav for sound, and .txt for plain text. These general file extensions are recognized by many pc users, but with new software coming every day, with it comes more file types which you might not know about.
