DOS internal command

0.01 sec.

A command capability within DOS at all times, such as Dir, Copy, Del, Ren, Type and Cls. The internal commands are part of DOS' COMMAND.COM file. If you delete COMMAND.COM, you can no longer command DOS to do anything at the command line.

The other kind of commands DOS can execute are external commands. Each external command, such as Format, Xcopy and Backup, resides in its own file in the DOS directory. If any of those files are deleted accidentally or purposefully, you can still execute all of DOS' internal commands and any external commands that are still left on disk.
