DiskAtlas Pro

About DiskAtlas Pro

DiskAtlas Pro answers one question fast: what is actually using my disk? Point it at a drive or a folder. It scans, then shows you the answer three ways at once — an interactive treemap where every rectangle is sized by real bytes, a ranked folder breakdown you can drill through, and a list of your largest files. Click any block on the map to zoom into it. Colour by folder, file type, or age. Filter files by size or by how long they have sat untouched. A duplicate finder verifies full file contents and shows how much space each group of copies is wasting. Cleanup suggestions describe regenerable folders, old installers, and large archives in Downloads — and select nothing on your behalf. Save a snapshot, rescan later, and see exactly which folders grew. Deletion goes to the Recycle Bin by default; drive roots, Windows, Program Files, and known profile folders are refused. Export any scan as CSV, JSON, or a self-contained HTML report. DiskAtlas Pro makes no network connections at all — no account, no telemetry, no ads. One-time purchase. Windows 10 version 1809+ or Windows 11; native x64 and ARM64.
