I have two hard drives in my tower; the C for OS (XP Pro) and software and the larger D for many files. The D was getting kind of full so I turned on Windows compression. Had a change of heart and turned it off, so about a third of files/folders were colored blue. Also had a plain text file where I stored numerous passwords. This file was among the items still colored black.
I decided to upgrade the mobo, CPU, RAM and the OS. I now have Win 7 64-bit. Was surprised to see that the name of the password file on the D drive changed from black to green. Finally discovered it was somehow encrypted. A lot of research revealed my only hope was to find something called an EFS certificate. Unfortunately it would have been on the now re-formatted C drive. But, wait; that drive was regularly backed up (Norton Ghost) to an external HD.
So what's the safe path to extract an EFS certificate from the C drive image file on that external drive?
