I didn't read that into it, but then the questioner could have worded it better, so its possible, but that would take 200 vtapes, and I don't think anyone has explored it that far for lack of sufficient storage space. And 200 50 megabyte vtapes on a 20GB drive would seem to be counter-productive even if it could be made to work with a disklist that almost defined each file. That would be like feeding the locate db into it for a disklist, very extreme. My 'common sense' if you can call it that, precluded drawing that conclusion. OTOH, my common sense has been known to be wrong too. :-) -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
