File Extension List

New applications are always being produced and it is important for our computer to know how to distinguish what kind of file it is accessing. By considering a files extension, our system knows exactly how to process that file.

The information needed to select which program to utilise to open a file is read from the files extension. A files extension carries clues to the format of the file and what variety of data it contains. As an example, some general file extensions include: .tga for pictures, .rar for compressed files, and .mov for movies. You may already be familiar with these common extensions but with the always growing library of programs and operating systems there are much more that you may have never seen.
