What are File Extensions?

A file extension is also known as a file name extension. It is a suffix appended to the end of a file name to indicate what kind of file type it is. You can easily know a file extension of a file, as it's separated from the file name by a dot. For example, the file extension of yourfile.doc is "doc" that tells the Windows that it's a Microsoft Word document. So the Windows will use Microsoft Office to open this kind of files.
