AtlayaView
Fast local disk space visualizer for Windows with cushion treemaps.
...AtlayaView is a portable, single-file, offline tool — no cloud connection, no telemetry. It includes an optional self-updater that checks the project's own release feed and can update itself in place.
Features include per-extension color profiles with an exclusive focus view, a searchable extension checklist, multi-drive scanning, and a UI available in German, English, French, Italian, and Spanish.
