Could you build this?

Partial Creating a web-based or basic treemap UI is simple, but building a high-performance, single-executable Windows native disk scanner that walks millions of NTFS file entries rapidly and renders interactive treemaps requires systems-level file I/O optimization.

What it would actually take: Typically built using C# (.NET AOT) or Rust/C++ interacting directly with the Win32 API and NTFS Master File Table (MFT) reader via `FSCTL_ENUM_USN_DATA` for near-instant disk scanning. The hard part is low-level MFT parsing, managing memory-efficient tree structures for millions of nodes, and maintaining 60 FPS zoomable canvas rendering.
