Turn a messy downloads folder list into a naming plan

Replace the bracketed details or make it yours using the form.

I want to turn a messy downloads folder list into a naming plan. Propose folders and filenames with a reversible mapping before any files move.

Use these inputs:
Filename inventory: [Add filename inventory]
Retrieval habits: [Add retrieval habits]

Create: File organization plan.
Separate supplied facts from assumptions. Ask only for missing information that changes the result.
Make the result specific enough to use and include a short way to check or improve it.
