What is a file extension?
A filename extension is a suffix to the name of a file applied to indicate what kind of file it is.
In some operating systems (for example UNIX) a file extension is optional, while in other operating systems (such as Windows) it is a requirement to identify the file type, and allow the operating system to know the software application that will be used to open it.
