Windows disk space analyzer
Topotree scans your entire drive in under 5 seconds and draws everything as an interactive map. The folder quietly holding 80 gigabytes stops being invisible the moment you see the picture.
Reads the NTFS Master File Table directly. A full drive with 750,000 files in under 5 seconds.
Switch between a treemap (bigger rectangle = more space) and a sunburst (rings show folder depth). Both update live as you drill in.
Filter by age to show only files not touched in 1, 2, or 5+ years. No other disk analyzer offers this.
Right-click to send to the Recycle Bin. Use the Collector basket to queue items from different folders and review the total before deleting.
Reopen any of your last 3 scans instantly without rescanning. A cleanup history dashboard tracks everything you've freed.
