I only ever use it to back things up, and I've been using it for eeeeeeever. I'm finally going through all my old crap, and it's ridiculous. I have literally every file, picture, and video I've ever needed from the past three years. And some things that I don't think I needed. I found a document that was just a list of movies that have made me cry. I also found a document that only has my favourite quote I ever found in a textbook; "One has then got to the position in which one cannot think that one cannot think about what one cannot think about because there is a rule against thinking about the X and a rule against thinking that one must not think about not thinking about certain things."
And I have a few dozen documents labeled "Project 1", "Project 2", "Project 3" and "Assignment 1", "Assignment 2", "Assignment 3", and "sijfosjgos", "aoeifjepe" and "2953845".
I think I'm just going to put it away now. No wonder I never bothered cleaning it out in the past.
