Hrmm thats interesting.. The reason why I have sooo many files is this. I have my main file(s) which is all lvl 99 characters that can whoop up on anything/anybody. All my other files are ones that I started to be better than my main file but usually never completed the task at hand. So all my other files have various levels that I stopped playing at such as level 78. Level 34. My newest is currently at level 24 and I bet I won't play all the way through on that one either.

I have also been known to take some of my files and put them on other memory cards to let my friends see what a good party is like and let them see if they like the game or not.
Thanks for your great input. Very interesting.
