I'm in the process of downloading ML, but I'm relatively new to macs and don't have my head around the basics. Can you someone please help with the following:

- what does a clean install mean?
- what happens to all the stuff I have on my Air (files/ apps from app store/ apps not from app store) during the upgrade?

I have a 2011 MBA 13" i7 4GB, if that matters....

Thanks :eek:
