Could you build this?
Partial The UI and treemap visualization can be assembled, but writing a high-performance Windows disk scanner that handles file permissions, hard links, and massive directories requires low-level Win32 systems programming.
What it would actually take: A responsive disk analyzer requires C#/C++ or Rust leveraging low-level Win32 APIs (e.g., directly querying the NTFS USN Journal rather than recursive filesystem scans) and memory-efficient treemap tiling algorithms (Squarified Treemap). Deep understanding of filesystem internals, sparse files, and parallel IO is essential to prevent desktop freezing during scans.
