File Extension List

New software is always being produced and it is essential for our computer to be able to tell what kind of file it is accessing. By considering a files extension, our system knows exactly how to access that file.

The data necessary to choose which application to utilize to access a file is taken by examining the files extension. A files extension contains tips to the format of the file and what kind of data it contains. Some of the more general file extensions include .exe for executables, .mp3 for sound, and .doc for documents. You may already be familiar with these general extensions but with the ever growing library of software and operating systems there are much more that you may have never discovered.
