Every file on your computer must have an extension to work. It is a type of identity which helps the user to know which category does a file belong and which software will be able to open it. It also acts as a guide for the operating system to assign the correct application to open a particular file when the user double clicks on it. When you choose a default program to open video files or images, the Windows OS checks the extension and stores the settings for next time.

No Extension Type Application
1 .MP4  .AVI  .WMV .MKV .MPG Video Any Video Player with codecs, like VLC Player, BS Player, Windows Media Player
2 .MP3 .MIDI .WAV .FLAC .WMA Audio Any Multimedia Player  like VLC, AIMP, Groove Music Player
3 .DOC .TXT .LOG .RTF, XML Document Any Word Processing Software like MS Word, Notepad, Apache Office
4 .EPUB .PDF .MOBI .AZW .IBA eBook Any eBook Reader or Browser or Adobe PDF Reader
5 .JPG .BMP .PNG .TIF .GIF Images Any Image Viewer program like Ms Paint, Photos, Windows Photo Viewer.

Changing the extension of one type to a different kind can leave the file corrupted, and it will not open. But if you want to pull a prank, then you try to change an image file’s extension to a document extension and send it to your friend and ask him to open it. And, then tell him how to change the extension back to an image file and try opening it. However, always use a copy for this type of fun so that in case the file gets corrupted, you still have the original. I have played that joke many times with a 0% corruption, but I have always used a copy image instead of original and first you have to make those extensions visible to you.
