The MKDIR command is used to create a subdirectory on a disk.  The command
may also be invoked using the abbreviated version MD.  The command format is
as follows:

      MKDIR [d:]path         or        MD [d:]path

If the command is entered without a disk drive identifier, the default is used.
Beginning the path with a backslash tells DOS to create the path starting at
the root directory (d:\).  The absence of a leading slash indicates you want to
create the directory starting at the current directory.  Only one directory
level may be created by each command (ie. you cannot create a path of two or
more directories that did not exist before the command).  Each subdirectory may
contain many subdirectories of its own, with the only limitation that the
length of any path from root directory to the desired level is less than 64
characters including embedded backslashes.  Some examples follow:

MKDIR B:\LEVEL1  - Create subdirectory LEVEL1 on drive B: at the root level.

MD LEVELN  - Create subdirectory LEVELN on the default disk in the current
             directory.

MKDIR A:\LEVEL1\LEVEL2 - Create subdirectory LEVEL2 on drive A: in directory
                         LEVEL1 (LEVEL1 must exist before this command).
NOTE **
* The root directory of a diskette can only contain a maximum of 112 file or
  directory entries, however subdirectories have no such limitation.  If you
  want to get a large number of files on one diskette, subdirectories can
  make this possible for you.
