The question I have is how much time does it take to maintain the folder system vs how much time does it save me? If I only need to pull that stuff rarely but it takes me an hour a week to maintain that system I've got 52 hours a year into the filing system. Say I have to pull that data back out once a month and if it was not sorted it would take me an hour to find it all. That's 12 hours spent vs 52 hours to make it faster. Not worth it IMO. There are many more things I'd rather do with 40 hours than spend them filing. Now plug in your numbers and decide that way. Look at the lifetime cost of sorting into folders vs the benefit.
