Type: Internal (1.0 and later)
Syntax:
RENAME (REN) [d:][path]filename filename
Purpose: Changes the filename under which a file is stored.
Discussion
RENAME changes the name of the first filename you enter to the second
filename
you enter. If you enter a path designation for the first filename, the
renamed
file will be stored on that same path.
Wildcard characters (* or ?) may be used with either the first or second
filename designation.
For more information about the RENAME command, see Chapter 2,
Using Common DOS Commands, in the downloadable book DOS the Easy Way.
