[Zope] Who created this object?

Hi, I'm in the process of cleaning up our production Zope server and I've found a folder which has one file in it. I don't know who created either of them and I'm wondering if they're redundant. I'd like to find out who created the both the folder and the file and, if possible, when it was last created. How do I go about doing this? Cheers for any help, Chris
