[AccessD] Archiving files with Winzip Command Line version

I was under the impression that it was faster to add.  When you add, it does
not have to recompress the files that are already in the zip file.  I think
that it does copy all of the existing data to a new file, adds the new data
to the file then copies it back over the original.

I believe that when you ask Winzip to 'add' files to an existing zip file is
that it actually extracts all the existing files to a temporary folder, then
it zips them all back up, including the additional files. That's when you
see the 'Copying Zip File" message.  So you really don't have any
performance hit to contend with if you do this manually.
