I'm relatively new to zope, so if I say something wrong please correct
me.

The first thing to learn about Zope is that it doesn't operate on files,
it works with objects! So you'll have to understand a bit about OO, the
second thing is that Zope is kind of an OODatabase. And that is the
answer to your question, your are deleting an element of a folder object
and then creating a new one, both are database trancsactions on the same
object - the folder object. So the behaviour is OK I think, as you'll
have to undo transactions that were made to Object X before the
delete-transaction in any database, I know.
