File Extension List
New applications are always being created and it is important for our system to be able to distinguish what kind of file it is accessing. That is precisely what a file extension is for!
To find out which program to access a file with, your computer first gathers the required information from the files extension. Data about the format and type of data contained within a file is designated by the file extension. A few of the most common file extensions include .exe for executables, .mp3 for audio, and .doc for documents. You may already be familiar with these typical extensions but with the always developing library of software and operating systems there are much more that you might have never seen.
