I'm looking to upgrade my internal HDD of my PS3. But, I want to backup my installed PSN games, (Burnout Paradise, Fat Princess etc.) most are downloaded from other users accounts so I don't want to have to re download. Note the games are already installed, I do not have the original .pkg files saved.
Is it as simple as just connecting via FTP and copying the game files off the internal hard drive? If so where would I find all of the game files needed?
