How is this better than being top level folders like school, receipts, car maintenance etc and then naming your files like:
2025-02-21 - car service receipt.PDF
Easy to find and see what is newest since it alphabetical by age and easy to search since the file name is descriptive.
Combine this with better search tools like powertools OK windows and it seems way more intuitive than this system.
Combine this by having the folder in a backup solution like google drive / Nextcloud / seafile etc and you can access these files anywhere securely.
