SoCalRoberta, it's been a couple of years so I really don't remember. I'm thinking maybe about an hour and a half, maybe 2 hours? I really can't be sure. If I were you, I'd set it to run overnight. I remember how much it would have cost to have someone do it, (and I really didn't feel comfortable having some stranger having access to all my files,) and how many CD's it would have taken. Scary! I knew there had to be an easier way so I went to Best Buy and found PC Relocator. It really is extremely easy to use. It will transfer files, your browser, (including your browser settings and email), fonts, even your Windows settings, pretty much anything you want. I went from '98 to XP and it felt like I never left home! ;) It was a real lifesaver. Good luck with your new computer! Coldrake
