No this can't help because I don't know how deep is my hierarchy: I've
delegated folder creations to at least ten persons.

I'm sure I can do it with ZopeFind, because Zope do it in the Find
(Advanced) tab, but don't know the exact syntax of: 

""" obj_expr = "not objectValues(['Folder'])" """ 

(which doesn't work because of nested " and ')

Actually I've put a <dtml-if> inside of my <dtml-in> loop, but it limits
my possibilities, especially because my result length is overestimated
(all folders vs only folders with no subfolders).

thanks anyway for your answer.
