@ mtone,

Thanks mtone. I didn't realise there was a MAC forum here. I will post the question there. Sounds like Phil's script is goning to be the best solution, but I might as wall canvas all the options, and perhaps learn something whilst I'm about it.

@ PhilC,

Thanks Phil. It sounds like you have done a great service for Poser MAC users. I'll definitely include a link to your page on "start_unzip.py" in the documentation. And thanks for clarifying that the MAC does indeed overwrite, rather than merge. I was not sure.

@ IsaoShi,

Thanks IsaoShi. I will look into dittoGui.
