OK I'm bit paranoid when it comes down to game save files. I have my PC and PS3 save files copied elsewhere and backuped in cloud. I just got external HDD for my Wii U as they didn't bother giving larger drive than 32gb which gets full from two digital titles. Two things I noticed was that HDD was formatted in some Nintendos own format so it's impossible to backup that without 1:1 copying and that moving or copying game moves save files with it! So now all my saves are only on my external HDD and there isn't any way to move save files individually or backup them?
