A single drawer is enough if you kill the pile before it starts.
You can fit a perfectly functional paper filing system in one drawer if you ruthlessly reduce what you keep and process paper as it arrives.
Most people fail because they think filing means keeping everything. It doesn’t. You only need three things in that drawer: an “action” folder (things you need to do something with), an “archive” for the past year (paid bills, completed docs), and maybe a few labeled hanging folders for recurring categories like tax, health, insurance, and home. That’s it. No subfolders. No color coding. No alphabetical indexing.
The real trick is processing, not filing. Every piece of paper that lands on your desk goes into the action folder first. Once a week you go through it: toss, scan, file in archive, or act. The archive is just a stack of manila folders (one per category) hanging inside the single drawer. After a year, everything in that drawer gets moved to a box in the closet or shredded. The drawer never fills up because you never let it.
A scanner helps. If it’s not a document that needs an original signature, scan it and recycle the paper. But even without scanning, the constraint of one drawer forces you to be honest about what matters
