File extensions are three-digit designations at end of a file name that indicate what format the file has been saved in. Common artwork file formats include: .eps, .jpeg, .pdf, .ps, .psd, .tiff. Common mail list file formats include: .csv, .txt, .xls.

In the DOS/Windows computer world, and UNIX as well, almost every file (anything on your computer that isn't a folder is a file in this context) must have some kind of extension. Example: index.htm would be a filename, where ".htm" is the file extension. On a PC in particular the operating system needs an extesion in order to determine what kind of file it is, and what to do with it when it is activated. With the internet, you may see extensions like .exe, .cgi, .asp, .htm, .jsp, .cfm, .tam, .php, .shtml, .pl, and many others.
