[AccessD] Archiving files with Winzip Command Line version

Andy,

That would work, except that in actual practice I'm *adding* files to an
existing archive, named according to the date the files are added to it.
So, the zip may legitimately exist before starting the archive, and I
can't kill it.

Thanks for the input, though.

Cheers!
Don

Don
You could use Dir in a loop to test for the zip existing. You'd have to
Kill
the file before too. Then set a time limit and drop out of the loop if
the
zip still didn't exist after that time.
