[Zope] exported root as backup now cannot access plone site to recover

Hi, Any help on this would be greatly appreciated. I'm new to zope and have been backing up by exporting the entire root folder - now I cannot recover the plone site contained within as when I import the .zexp the entire site comes in under a folder called zope. Inside this folder is the plone site but as it is now not in root it cannot function. I'm pretty desperate for some help - how can I extract the plone site from the entire site backup and place it back under root? I would be grateful for any help as a lot of people have been contributing to the site via cmfplone. Thanks Rhys
