Some files must have specific extensions. For example, the .PRG extension tel l s
your computer that the file i s a n executable G E M application. If you remove the
extension .PRG from the filename, the computer w i l l not recognize the fi le as an
application.
Appl ications often use a specific fi le extension. This extension i s automatically
assigned to any file the appl ication creates. For example, word processors often use
. DOC or .TXT as an extension for documents. See the documentation suppl ied
with the appl i cation for more information.

can be recognized. These extensions should be used only for executable files:

cannot be opened i f the extension i s deleted or changed.
