Scale-drawn visual treemap of every gigabyte on disk.
DiskUni's Storage module implements a state-of-the-art Squarified Treemap algorithm rendered at a blistering 60 FPS. Every folder and file block is drawn geometrically proportional to its exact byte size on disk. Easily zoom into nested folder hierarchies, pinpoint runaway log files or forgotten video renders, and filter the largest items with intuitive category chips.
Optimal aspect-ratio rectangular packing for maximum legibility
Smooth GPU canvas pan, zoom, and drilldown
Navigate through 50+ nested directory layers instantaneously
Traverses 1,000,000 files in under 850 milliseconds
Proportional Area Representation
If a folder consumes 40% of your disk, its rectangle occupies exactly 40% of the visual treemap canvas.

How does the Squarified Treemap differ from traditional pie charts?
Pie charts become unreadable with more than 7 items. The Squarified Treemap packs hundreds of directories simultaneously into human-readable rectangles, preserving area proportions perfectly.
Can I inspect hidden system files and developer caches?
Yes! DiskUni can inspect hidden AppData folders, Docker virtual disks, WSL images, and package caches with full permission management.
Can I reveal the exact file in Windows Explorer / macOS Finder?
With a single click or keyboard shortcut (Enter), DiskUni reveals the highlighted file in your native file explorer.
