Mine is mostly purpose driven. There are the fundamentals folders. Each have their own naming and categorization strategy. Then there are the folders inside these folders to help with the above, and there are the container folders, which are mostly content types.

The fundamentals projects are often automated or augmented with tools. If not I just think about what are the primary keys I would have when I'm looking for it (and I don't mind duplicating if the file is final, like receipts or contracts). For stuff you're currently working on, you can use versioning and timestamps to have stuff to file.

It has become surprisingly easy to find files after that. And with tools like spotlight (macos), the result makes much more sense.
