rmdir

The logic here is a bit strange and this copies MRI (Ruby) which may not be language agnostic, but windows (win7 and others) automatically mark folders as read-only when it contains other files and folders within it. This document explains more: http://support.microsoft.com/kb/326549 I think the logic is based around idea that if you removed all other files it would be empty but will stay marked as read-only.
