What Diskus is
Diskus is a free Windows utility that visualizes disk usage with interactive sunburst diagrams. It scans files and folders on internal, SSD and USB drives, helping locate large directories. Clicking rings zooms into folders, while breadcrumbs provide a route back; users can set diagram depth and size limits. Drives appear in tile or list views with capacity bars and color cues at 80% and 95% full. A resizable file list shows folder contents and sizes, supports sorting by name or size, and remembers its width. Real-time name search works within the current folder, with settings for minimum file size and hidden files. Items can be collected from a context menu or by drag and drop, then moved to system trash with a short-time undo option. Other actions open folders in Explorer or preview them with Quick Look. German and English interfaces are available. Windows downloads come as installer or portable versions, with releases on GitHub. The first scan of large drives may take a few seconds. The plan costs nothing; macOS and Linux are coming soon.
