Volker -

Given that this data came in all at once in an Import (from an
unusual server type, VM), it is probably concentrated on a few
volumes. To settle the issue, I would perform a Query CONtent on the
volume(s), to a disk file, and browse that listing to see what's
actually out there. (Query CONtent is inexpensive, so little
concern.) Could be interesting.
