I need to get the old XP data over to the new W7 computer. I also have a 1TB external drive. I need to get my files and photos and such moved over. Help please, I'm not a computer expert and I can't find anything on MS website. The easy transfer is not recognising the .dat on my W7. I was able to use easy transfer on the XP to the external drive (Collection Complete) but when I use W7 easy transfer it is looking for .mig data.
