Oh gosh, this is such complicated stuff!
Trouble with me is, there are things in sets/compilations that I don't want in my game so I have to have some full sets installed and some partial sets. I obviously make it much worse for myself doing it this way, but there are just some things I can't stand seeing in my game and it really bugs me if they are there!
But I am thinking of doing an overhaul of my back-up stuff so this thread will be very helpful, thank you.
Edit: Oh yeah, and for people who hate making collection files for them all - perhaps this link would be useful: http://aznsensei.blogspot.co.uk/2012/07/store-collection-files.html
