Removing Directories
You may sometimes want to remove directories you no longer
need. A directory must be empty, however, before you can
delete it. If it contains any files or subdirectories, MS-DOS
displays an error message and does not delete the directory.
(Use the DEL command to delete the files in a directory.)
