Yes, of course. Thanks. I forgot the context. I'm tired today.

So the correct session is:

 >>> from zope.app.folder.interfaces import IFolder
 >>> from zope.component import getUtility
 >>> getUtility(IFolder, 'foo', root)
<zope.app.folder.folder.Folder object at 0xb6c68b2c>


But what did you mean as "set the site"?
do you mean with hooks.setSite() ?
