Maybe use a good compression format, not the poor quality that is Zip...

I knew you'd bring that up. Zip is widely recognised and supported, and even on-technical ppl generally know how to handle zip file (I work in IT support, and I know this from experience). Also, zips are handled almost transparently in XP or by earlier Versions oif they install the right software.

For the sake of an extra few % compression is it really worth switching to something more obscure like .rar?
