File Extension Info!

File extension is also known as filename extension, it is used as suffix at the end of a filename. With the help of file extension it becomes easy to understand what kind of file it is. For example the user can understand that file “computer.jpg” is a JPEG file format that is based upon the “.jpg” file extension, “document.doc” is a Microsoft word document and “readme.txt” is a text document. Filename extension was originally used to easily determine the file's generic type.

Generally most of the file extension consists of three characters, however it may be more like (.gadget, .tiff) or it may be fewer (.ps, .h). Whenever user double click a file then the computer uses its file extension and with it enable the user to know about the file that are opened.
