File Extension List

New applications are always being created and it is important for our computer to be able to tell what sort of file it is accessing. That is precisely what a file extension is used for!

To detect which application to access a file with, your pc first collects the essential information from the files extension. A files extension contains hints to the formatting of the file and what variety of information it contains. As an example, some common file extensions include: .jpg for images, .rar for packed files, and .mov for video. 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.
