Thanks for clarify that.

FYI: I once had a situation where Zope wouldn't start due to corrupted data.
But, when I copied the Data.fs file to another installation, everything worked
fine.
When I tried putting a Data.fs from a fresh installation in place of the
corrupted one, Zope still wouldn't start.  I finally discovered that deleting
the .index file was what it took.
