So I put the vast majority of items in our file drawers into PDF's via a ScanSnap 1500M (Thanks for the reco MPU - you know MacSparky and Katie Floyd ). One of our big appliances just acted up. I have the PDF's of our files in Yojimbo and was quickly able to access the manual (I had downloaded this vs. scanned) and go to the trouble shooting section AND find a receipt with the phone number to the service company. Total time was about 45 secs. of searching. Got the model number serial number...you name it, I found it.
So much win!!!!
