Feature Request: Folders

It would be great if I was able to create folders because then I would be able to sort all my files much more easily.

Also, I want to give a thank you to the dev for being so active on this project.

The issue names no files, tests, or entry points. First clarify the intended folder behavior and scope, then inspect the project structure to locate file-listing and upload flows; done means users can create folders and organize files as intended, with coverage for the agreed behavior.
