Dive deep into your disk space
Interactive visualisations, duplicate detection, and smart cleanup tools for macOS, Windows, and Linux.
Stuff Diver is a desktop app that helps you understand where your disk space is going. Select any folder and instantly see its contents brought to life through seven interactive visualisation modes, find duplicate files wasting space, and clean up with intelligent pattern-based tools.
| View | Description |
|---|---|
| Rings | Concentric rings showing folder hierarchy at a glance |
| Treemap | Space-filling rectangles sized by file/folder size |
| Pie Chart | Circular breakdown of top files |
| Bubbles | Interactive circle packing with drill-down navigation |
| Table | Sortable list with full file details |
| Histogram | File size distribution across 9 size buckets |
| Timeline | Files grouped by modification date |
- By Age -- gradient showing how recently files were modified
- By Type -- colour-coded file categories (images, video, audio, documents, code, archives, data, executables)
- By Folder -- distinct colours per top-level folder
Three-tier duplicate detection:
- Gold -- exact content matches (SHA-256 hash verification)
- Silver -- same name + same size
- Bronze -- same name, different sizes
Each group shows how much space is wasted so you can prioritise cleanup.
Pattern-based cleanup that detects and categorises:
- System caches and temp files
- Log files and thumbnail caches
- Old downloads and broken shortcuts
- Duplicate applications
Preview what will be removed and how much space you'll recover before committing.
Compares current and previous scans to project growth trends -- daily/monthly rates and an estimate of when your drive will fill up.
Background monitoring with configurable intervals (6h / daily / weekly). Get system notifications when a folder grows significantly. Runs in the system tray when minimised.
