By default you cannot view file extensions as it is hidden. So what you can see is just the name of the files. But times are there when you need to change the type of certain files in order to run them in your system that is to make those files compatible to your machine. In that case you must make the file extensions visible and change according to your requirements. A question may arise in your mind that why do we need to change the format. The reason is that many software applications does not support every type of files. E.g. all movies do not run smoothly in all types of files. This is because of the extensions of the files are not compatible with the media applications.

One thing to remember is that in order to change the file extensions you must always be logged in as an administrator.
