- Path.renames(old, new)
Super-rename; create directories as necessary and delete any left empty. Works like rename, except creation of any intermediate directories needed to make the new pathname good is attempted first. After the rename, directories corresponding to rightmost path segments of the old name will be pruned until either the whole path is consumed or a nonempty directory is found.
Note: this function can fail with the new directory structure made if you lack permissions needed to unlink the leaf directory or file.
