NTDOC,

Tested the script with winzip 8 +cmdline and wzzip switches

Tested the script with winzip 9 beta +cmdline and
wzzip switches

Winzip 8 reads the line and if it sees -v or - v in the string passed to the command line it will fail.

ERROR: option -v, -vi cannot be combined with option -a, -d, -f, -i, -u
Program is terminating!

Winzip 9 does not have this problem.

Perhaps I should test other products for the archive job too.
