The TREE command displays all the directory paths found on the specified
disk drive.  The command format is as follows:

            TREE [d:][/F]

If no disk drive is specified the current drive is assumed.

There is only one option available:

/F  - All the files in each subdirectory are displayed.

Each directory is checked (starting at the root), and its subdirectories are
listed.  Each one of these subdirectories are then checked for more
subdirectories until all directories in the tree have been presented.  The
search then continues at the next subdirectory in the root.  If the /F option
is specified, all the files contained in each subdirectory are displayed.

Examples:

TREE /F  - Display a directory tree of the current disk with filenames.

TREE B:|MORE  - Display a tree of the diskette in drive B: one screen at a
                time (see help files MORE and PIPING for details).
