I have no idea of what ZZZZZZZZZZZZZZ folder you are referring to, unless you simply misnamed it, but that shouldn't effect your ability to delete it, unless for some reason you don't have ownership of it, as the last post dealt with. The only other time I've found I couldn't delete a folder, is when it contained other files & folders. This is not always a problem, but when it is, I delete those internal files & folders first, then the root folder should delete also.
