remove system files from zip

You must use the command line zip. I had made one, but I can't remember what I did.

As another option, you can create this Automator Service to clean the zips after you create them.

Build this Service in Automator, save it with a short name, then right-click on your zips and select the name from the Services menu.

Here is the shell script code which you can copy and paste into the action:

for f in "$@"
do
          zip -d "$f" ./__MACOSX* \*.DS_Store
done

Glad that helped. I wish I could remember the commands to make the clean zip in the first place. When I looked through the zip man page, nothing really struck me as familiar, so I went with that other angle.
