I'm not exactly sure what your asking, but we are using the file system 
mapping.  Here is the relevant portion of our zope.conf

%import Products.Ape
<ape-db main>
  <ape-storage>
    mapper-variation filesystem
    <ape-fs-connection fs>
      basepath $INSTANCE/var/fs
      hidden-filenames _|\.svn|.+~|.+#
    </ape-fs-connection>
  </ape-storage>
  mount-point /
  scan-interval 2
  cache-size 10000
</ape-db>
