Many I always wondered: shouldn't the crc-32 and crc-16 of zip and arc files be unique enough to validate any file? Why can't we just put these checks and the length of a file on the net. If you insist, then of course you could add any propietary validation values like the ones obtained from the validate program. But I'm pretty sure that most people trust their favorite zip or arc program more than some kind of a so-called validate program. - -- Sincerely, | berg@cip-s01.informatik.rwth-aachen.de Stephen R. van den Berg | ...!uunet!mcsun!unido!rwthinf!cip-s01!berg
