It must go somewhere where it is executed (to become effective). A product's "__init__.py" is one natural place.

I am having trouble with: from Products.CMFCore.FSFile import FSFile ... registerFileExtension('html', FSFile)

Products.CMFCore.FSFile does not exist on any of my Zope servers. Is this another product/patch/add-on?

That is strange: "FSFile" is part of "CMFCore" as well as "DirectoryView" (aka "Filesystem Directory View"). Have you "CMF" ("CMFCore" would be sufficient) installed? Which version? Use 1.3.3 or 1.4.2. -- Dieter
