This is a pain to do in my house. We have two people playing FF while sharing two computers. Aside from that, each character that you make is listed with separate folders and they do not use the character names on the folders. I was able to figure out which character was which on my machine because I knew the order of creation and was able to look at the files creation dates and luckily he had only logged one of his characters on my machine at this point. I also noticed that deleted characters still had folders left behind. I'm just glad that I looked into mine now with only 7 characters active, 2 deleted, and 1 from another account. Had it been down the road sometime and with no character identification other than a 5 string of alphanumeric code at the end of a longer string of alphanumeric code, I may have just given up! It would be nice to have an in-game feature to take care of that or at least character and world labeling on the original folders.
