The method I used for keeping track of memos, reports, and the like, I called "Vertical Chronological Filing System". In other words, after using an item throw it on the top of a pile. This also works for CDs. What you use frequently naturally rises to the top of the pile. Every so often, throw away the bottom half of the pile.
This is not completely a joke...it actually works as well as any other system I tried. People were astonished that I could come up with memos in a few seconds ("let's see..down about 3 inches") that would take them an hour of searching through file cabinets.
