        Download this file. By default, the file is saved in the current working directory with its
        original filename as reported by Telegram. If the file has no filename, it the file ID will
        be used as filename. If a :attr:`custom_path` is supplied, it will be saved to that path
        instead. If :attr:`out` is defined, the file contents will be saved to that object using
        the ``out.write`` method.

        Note:
            :attr:`custom_path` and :attr:`out` are mutually exclusive.

        Args:
            custom_path (:obj:`str`, optional): Custom path.
            out (:obj:`io.BufferedWriter`, optional): A file-like object. Must be opened for
                writing in binary mode, if applicable.
            timeout (:obj:`int` | :obj:`float`, optional): If this value is specified, use it as
                the read timeout from the server (instead of the one specified during creation of
                the connection pool).

        Returns:
            :obj:`str` | :obj:`io.BufferedWriter`: The same object as :attr:`out` if specified.
            Otherwise, returns the filename downloaded to.

        Raises:
            ValueError: If both :attr:`custom_path` and :attr:`out` are passed.
