I got a copy of windows 7 professional and it will not allow me to just upgrade to it from vista home basic so I have to back up a lot of random stuff onto DVDs. I 136GBs of steam games and I would rather not have to download them all again once I install windows 7. Is there a way I can divide my 136gb steam apps folder amongst a bunch of DVDs then extract it into a new steam installation in windows 7? I would rather not use 7z to make a bunch of seperate files because it would take so long. Though if you know of settings that would allow it to compress everything into a bunch of seperate files faster please tell me!
