A lots of short form are using out there to describe a file like .doc for document, .flv for flash video, .mp3 for audio etc. so there could be a hundred or thousands like this but in this post i m sharing as much as possible.
I should hope this most will help you to understand programing language of a operating system. this short forms will also help you to recognize a file type without opening that file and also will help you to save a file as with its extension like 'thispage.html' etc.
So, lets see and have a try how much we can remember for future.
