What's with this filing system?

I just can not believe the amount of paperwork involved in becoming a foster parent. And how I can not find some of it.  As I asked in Facebook, how is it that I can still find Thomas's kindergarten fingerprints, my college ID, the sales contact from the Colt (bought in 1989, given away in Katrina), and the expired passports for both boys, but I can't find my Social Security Card, or the current vaccination records for the dogs?  I never throw anything away, unless I'm going to need it this week.
