  OK, I can do that, but my scans will still fail due to archives in tmpdir
(see below).

        No, I have not found a virus in these large files.  But ignoring
them defeats the purpose of scanning for viruses.

  OK, so it's the archives' that are being extracted to tmpdir.  I'll have
to do more testing to find out the general size I'll need:  I'm running on
multiple oses and several hunderd servers.

  I do scan only 1 file at a time, I'll ignore MaxThreads.

Thanks Edwin.
