File Extension List

New programs are always being produced and it is important for our personal computer to know how to tell what kind of file it is accessing. That is exactly what a file extension is employed for!

The data required to choose which software to utilize to open a file is learned from the files extension. A files extension contains clues to the data format of the file and what variety of information it contains. As an example, many common file extensions include: .gif for images, .rar for packed files, and .mov for movies. You might already be familiar with these typical extensions but with the ever growing library of programs and operating systems there are many more that you may have never discovered.
