The files that one deem important vary from person to person. How do you expect a reasonable answer to a question such as yours?
"I would delete the anime porn." -me
"I don't wan't to delete the anime porn" -you
"Well I like to hold on to the pictures of my pug" -me
"I don't have a pug so I can't relate to that" -you
So this all comes down to one thing. I have a pug and you don't. Oh yeah, I have a chihuahua as well.
