            - ``name``: The base name of the file/folder
            - ``path``: Absolute path to the object.
            - ``id``: URL-safe base64 encoding of the ``path``
            - ``children``: Only present if ``type`` is ``folder``. A list of all
                children of this folder, each having the same representation.

        Args:
            fid (str): the base64 encoded url safe ID for the path to the root folder

        Example::

            http localhost:8000/files/tree/{fid}
