If you like CMD programming, here is a challenge for you: write a CMD batch file that solves the Hanoi problem. You start with these folders:

    
and you must end up with this state:

      

You probably know the rules of the Hanoi problem. Mapped in the command shell terminology these rules are as follows:
1) You can move one file at a time, and only between the Stack1, Stack2 and Stack3 directories.
2) After you move a file into a target directory, it should always appear first in the DIR command (that is, lexicographically, must be the first one).

Good luck!
