I guess it’s partly a mentality thing for me. I’ve had numerous cases of sadness that I couldn’t produce a necessary document, and gladness that I was able to pull up something presumed long lost. For me, it’s easier to save everything “just in case”. It all adds up to less than 50GB so it’s not an enormous amount of data to store by current standards.

Seriously, a couple cases of “sorry, I don’t have proof to back up that tax deduction” or “hey, here’s the receipt proving that our TV is still covered by warranty!” make it all worthwhile.
