SpaceSharpApp/SpaceSharp ? reverse-engineered prompt

Build me a Windows app that shows where disk space is going in a fast zoomable treemap.

I want to scan a whole drive or a folder, then see every file and folder as a box sized by how much space it uses. Let me zoom into folders, pan around, and right click items to open them, inspect them, filter by type, or send them to the Recycle Bin without leaving the map. It should also let me search and filter in plain language, like videos over 500MB older than 1 year, and dim everything that does not match.

Please make it save scans so I can reopen recent ones quickly and compare against the last scan to see what grew, shrank, or is new. It should be a single portable exe for Windows 10 and 11, with a clean modern UI, and it’s fine to look up current docs online if you need to.
