New applications are constantly being produced and it is essential for our personal computer to be able to distinguish what kind of file it is accessing. That is precisely what a file extension is for!

To determine which application to open a file with, your system starts by gathering the essential data from the files extension. A files extension carries clues to the data format of the file and what kind of data it carries. For example, many common file extensions include: .gif for images, .zip for packed files, and .avi for movies. You might already be familiar with these general extensions but with the always growing library of software and operating systems there are many more that you may have never seen.
