[Zope] Extract Files from ZODB

I have a ZODB that was being used by Plone to store files(Word documents, Images, etc.). Plone is no longer working. I want to extract (retrieve) the files from the ZODB. Is this possible? If so, how is this accomplished. Note: I cannot access Plone or anything in Plone because it is not working. I am looking for a solution that involves working only with ZODB through Zope, not a procedure that attempts to troubleshoot Plone.
