The Delete command serves 2 purposes:

    o  Delete files by File-id

    o  Delete complete directories and directory trees very fast

 Deleting files by file id's (with the /FILE qualifier) can be
 useful in removing files which are no longer in a directory (e.g.
 files marked for delete). Deleting a directory (with the /DIRECTORY
 qualifier) is many times faster than the normal DCL delete command,
 especially for large directories. The /TREE qualifier can be used
 to delete a complete directory tree with just one command. The /FILE
 and /DIRECTORY command cannot be combined.

    Syntax :

       DELETE device/FILE=file-id
       DELETE full-directory-file-name /DIRECTORY(/Qualifiers)
