[Zope] Filesystem Directory View, etc.

Hi all, I'm trying to get some Webalizer stats accessible from a Zope instance. The problem is FSDV transforms any .html .htm .dtml document (it just rips the extension). I don't know why it does that, nor how I could tell FSDV not to do it, but it's a little rude since Webalizer builds many html pages that are linked together according to their full names (name+ext). So the navigation from imported Webalizer pages into FSDV is broken. Also note that while it's possible to tell Webalizer to produce various extension names for the files it builds, I don't see how to tell him NOT to produce any. Anyone has an idea how to proceed ? Thanks, Aurélien.
