Thank you all so much for your help.
Ben, you are right, I did think of the security issue. But my boss
kept telling me there was a way to do recursive find. I searched the
web and found I could use an applet and then a perl script in the
backend. However, boss did not approve using applet.
Ted, the zip method was my last resort which I have working.

I think it is possible to give signed JavaScript the permission to do
this (similar to signed applets). But I've never looked at the details
and it's off-topic in this group anyway.

AFAIK, works only on Firefox. So, if that is a suitable restriction for
the OP, the next place to check is Firefox documentation on how to do
it.
