Our IT Deparment says that it is not possible for zip files (unzipped at
180MB) of data to have come through the firewall without being detected.
AND, it is also not possible that this large volume of files could have sat
on the C:\ without being picked up.
Not sure how they are scanning - but if they are scanning for a volume
retrospectively, how could they be sure?
I'd really appreciate your comments.
