File extension?

A file extension is a suffix to the name of a computer file, which defines and determines easily the file's generic type. In Windows and DOS operating system file extension is a requirement whereas, in some other operating system such as UNIX it is optional. Usually the file extension consists of two, three or four characters following a period.
