Diskaroo

Diskaroo とは？

See where your disk space went, and free up the room you don't need. Diskaroo is a native treemap visualizer for macOS, Windows, and Linux with drill-in navigation, smart filters, duplicate detection, and a collector tray. Unlike browser-based or Java-wrapped tools, Diskaroo is built natively per OS, so it feels fast and familiar everywhere. The collector tray lets you queue files and folders from anywhere in the scan before deleting, so cleanup is deliberate, not a one-click accident.
