Command: mkdir
  MKDIR creates a directory or subdirectory.
Syntax:
  MKDIR [drive][path]pathname
  MKDIR [/?]
        drive     The drive letter where you want to create a 
                  directory, e.g. C:
        path      The pathname which already exists, e.g. if you are 
                  already in a directory.
        pathname  The name of the directory you want to create, 
                  e.g. \example. This may also be the name of a
                  subdirectory.
Options:
  /?  Shows the help.
Comments:
  You can also use MD instead of MKDIR.
  If you simply type "MKDIR PATHNAME" the directory will be created 
  in the momentaneous direcory. Means: You create a subdirectory.
  In pure DOS the directory name must not be longer than 8 letters.
  MKDIR is a command internal to command.com and needs no other file
  in order to work.
Examples:
  mkdir c:\test
  mkdir c:\test\testx
    or if you are in c:\test:
  mkdir test2 (creates c:\test\test2)
