You will run into problems however if you want to delete from a tree while ignoring certain named directories. Directories must be empty before they can be deleted, so you must use "topdown=False", but to prune a search you must use "topdown=True". At least I think that was the problem I had with my deletion script a while back. ~Sean -- http://mail.python.org/mailman/listinfo/python-list
