OpenDisk

OpenDisk shows you exactly what's using your disk - and helps you get the space back.

Point it at a folder or drive and OpenDisk maps every file and folder as a beautiful, interactive sunburst chart. Each ring goes one level deeper, so the biggest space hogs jump out instantly. Hover any slice for its exact size, click to zoom in, and browse a fast, sortable list beside the chart.
