Yep.

I can get precisely the same effect with PKUNZIP. So why bother to
change to Polyxarc which I dont use for all my other archive stuff and
have no idea how bug free it is ?  I have extensively tested PKZip when
it upgraded to make damned sure it really is doing what its supposed to
do and not fucking up. I use it all the time for all my other archive
file work and if it had a problem I would have seen it by now. Or more
legalistically, if there are remaining problems, they are very subtle
ones. I dont have that knowledge about Polyxarc.

And that mode of operation doesnt particularly suit me anyway, I
dont WANT to delete the archived PKTs. I want to keep them for a bit,
atleast until the QWK has been read, so I can rerun the PKT->QWK if
there is some fuckup or use the original archive PKTs to apply a new
version of PQWK to and see if I get the same QWK produced from it.

There are other ways around that like a copy/compare/delete op.
Not that I bother, I backup thoroughly so if some problem ever
arises, the backup is available. And protects me against other
problems like the drive dying or the machine getting stolen.
