I recently upgraded from windows XP home edition to Windows 7 professional. Unbeknownst to me at the time, the easy transfer file wizard creates .dat files that are not recognizeable by any future windows operating systems. So now I have many years of accumulated data on an external hard drive that I can not get to and use. I have licensed copies of both the XP and the Windows 7. I have searched through both of them and found several things, the most important being there is no way they explain to get these .dar files back. Can anyone help me?
