+The disk space used by the articles fetched by both the cache and

@item u
User defined specifier. The next character in the format string should
be a letter. Gnus will call the function

+The one problem common to all users using the agent is how quickly it
+can consume disk space. If you using the agent on many groups, it is
+even more difficult to effectively recover disk space. One solution
+is the @samp{%F} format available in @code{gnus-group-line-format}.
+This format will display the actual disk space used by articles
+fetched into both the agent and cache. By knowing which groups use
+the most space, users know where to focus their efforts when ``agent
+expiring'' articles.
