Hmm. I don't know of a script that does both the zipping and unzipping. I think the poseter may have misunderstood. This was the thread I sent people to (and still do during training and workshops). Paul, that post is in the first couple pages of this thread, I believe, and is (your) two separate scripts in one .zip file. Do you have a site where users could make donations to your cause?
Seriously, I'd love to send them there.
