Hard or Soft

I'm almost done with clearing up my room. I guess whatever remains now is just for me to save all my stuff onto my hard disk and teach whoever who's taking over my job how to access my files. There's a lot of information I've been keeping over the years and when a colleague asked me for my documents in hard copy, I was quite surprised as I prefer to keep mine online in soft copy. I thought most people do since it saves filing space, not to mention the amount of paper that needs to be printed for all these documents! But my colleague comes from the old school who still prefer to see paper.
