Back in school a class mate used a bat file to recursively create a directory an then enter it and repeat.

The directory also ended with ascii 255 which looks like a space and when placed at the end is invisible.

This was in msdos and there was no mouse or autocomplete, also no deleting of non empty directories.

The teacher finally gave up and admitted he could not solve it.

You had do make a new script first to traverse to the inner most dir, then recursively back trace removing directories.
