permission question

If I'm going to relegate rsync to the trash bin due to it not
supporting Windows permissions well enough to be useful, I've got
other Windows recursive copy tools I use that don't preserve
permissions either.

I can't tell you how much I love Windows security permissions.  :(

In the mean time I have a huge number of folders now on my destination
drive I need to delete.  (over a million files it seems).

Neither cygwin, nor windows says I have permission to delete them.

Any idea how I can do it short of reformating.
