Seth-
Thanks for the extensive reply.  I am excited that this is even possible.

I have to say that I am lost by the "magic" you describe.  I don't
understand what you mean by the 4b82... value should be replaced by
the find | xargs remove all command.   That command looks like it just
deletes all the "." file names?  But when you say replace I thought
you would mean I need to generate a new value to replace that magic
number??  Confused...
