I just built a new computer and need to transfer my files from my old Hard-Drive to my new one. I already have Windows 7 installed on the new PC and wonder if I should connect my old Hard-Drive to my new PC or take new hard drive out and transfer files on my old Vista machine? Also what would you guys recommend for the transfer as the best way? Just drag and Drop? This is my first time transferring files so a little nervous about it.
