Give webdav plugin a clean temp directory

        if use_temp_files is None:

            # Default to True to avoid memory issues with large files.

            props["use_temp_files"] = True

            props["temp_path"] = props.get("temp_path", tempfile.gettempdir())

            props["temp_path"] = props.get("temp_path", tempfile.TemporaryDirectory(prefix="webdav_"))

        extra_props: Union[FilesSourceProperties, dict] = opts.extra_props or {} if opts else {}

        handle = WebDAVFS(**{**props, **extra_props})

        return handle
