File Extension List

Our system requires a way to access particular files and specify what applications they are affiliated with. By considering a files extension, our personal computer knows exactly how to access that file.

To determine which application to open a file with, your computer starts by gathering the required information from the files extension. A files extension contains hints to the format of the file and what variety of data it holds. Some of the more 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 ever developing library of programs and operating systems there are much more that you may have never seen.
