Code: each project in its own folder. Docs: date sorted mess with a twist. In over 30 years of using a computer, I've only rarely gone back to stuff I haven't touched in months. So when I notice that old files I no longer care much about are starting to pile up, I create a folder and move applicable files into that folder for archival purposes. I've a few exceptions for important papers, like contracts and invoices.
