Hello, I need to make a page that allow to insert/delete/update archives from zope. For that I will need to have a tree of the objects(like directories and subdirectories).

I want to know if there is any example of that or how can I do it. Where are your archived documents: in ZODB, in a relational database, in the file system?

How is the hierachical structure defined? There is a HowTo on advanced "tree" use on zope.org. Maybe, you look at it. Dieter
