Your disks, as a city you can fly through. Treemapolis turns the Windows shell namespace into a 3D treemap: every folder is a slab, every file a building as big as it weighs on disk. It is a technology demo of DirectX 12 driven from C# and .NET NativeAOT, and it is also a genuinely fast disk space explorer.
