File Extension List

Our system needs a way to access specified files and determine what programs they are associated with. That is exactly what a file extension is employed for!

To determine which program to open a file with, your computer starts by gathering the necessary information by examining the files extension. Information about the format and type of information contained within a file is indicated by the file extension. Some of the most common file extensions include .exe for executables, .mp3 for audio, and .doc for documents. You might already be familiar with these common extensions but with the always growing library of software and operating systems there are much more that you might have never seen.
