The other day I needed to create lots of directories for file storage with the following structure:

0/
    0/
        0/
        1/
        2/
        ...
        z/
    1/
        0/
        1/
        2/
        ...
        z/
    2/
        ...
    ...
    z/
        0/
        1/
        ...
1/
    0/
        0/
        1/
        ...

It is not so difficult to create these directories with a php or any other server side scripting language script, but I also made a simple BATCH script as a common Windows solution.
