+    :class:`ExtFileStore` instances. The delivered file_id contains
+    the file id marker for :class:`Applicant` object and the

+    generated file id.

+
+    File store name choosers like this one are only convenience
+    components to ease the task of creating file ids for applicant
+    objects. You are nevertheless encouraged to use them instead of
+    manually setting up filenames for applicants.
