detecting saved game files

[Prisma101]

Here's the situation:

I am reformatting my computer and don't want to lose my saved files. I moved my game to my portable hard drive and can play it on my other computer off of my hard drive. However, no saved game files show up.

I read through forums and found the files on my original computer (user/my games/king's bounty/etc..), but what can I do with that folder/those files to transfer them to either my other computer OR my portable hard drive so that the game detects these files when I play.

And if anyone can tell me why Diablo III crashes/gives me blue screen of death after 15 minutes of game play, that would be great
