Yep. I use an amazingly cool system "straight line" filing system from Smead called "Viewables". I saw it on the shelves one day at Staples. It comes with software (Windows only, I think), 16-label sheets for your printer, and plastic tabs. It'll even remember which labels you've used up already on the page, so you don't have to do 16 at a time.
It's totally addictive. I went through and redid all my files with it.
