[Zope] Re: Is there a "Virtual Folder" Product??

Hi everyone, my last question regarding the MFolder product would be how to make the root folder of a Zope installation a MFolder? So far I can only add new MFolders but not change an existing (= / root) to that. It would be great if Dieter or anyone else who's using MFolder could help me on this. Thanks in advance, Philipp Robbel
