See What's Eating Your Disk —
Then Track How It Changes.

"My C Drive Was Eaten by AI Models"
If you're a developer working with AI/ML, you know the pain. HuggingFace cache, Stable Diffusion models, npm dependencies, Docker images... your disk fills up silently, and you have no idea where all that space went.
Hard to Find
Hidden caches scattered across dozens of directories with cryptic names you'd never think to look for.
Time Consuming
Manual exploration takes hours with Windows Explorer — and you still can't be sure you've found everything.
Risky Deletion
Afraid of deleting critical system or project files. One wrong move and your dev environment breaks.
Everything you need to master your disk
Fast, smart, and featherlight — built for Windows power users and developers.
Lightning-Fast Scan
Parallel Win32 engine powered by Rust and rayon. Scans 500,000+ files per second on SSD — your entire drive in seconds, not minutes.
Disk Timeline — Track Changes
Automatic snapshots saved after every scan. Compare any two dates to see which directories grew, which shrank, and by how much. Nothing changes on your disk without you knowing.
AI-Powered Analysis
Click any directory for an AI-generated explanation of what it is and whether it's safe to delete. Works on individual folders and on snapshot diffs.
Visual Space Discovery
Tree-based navigation with color-coded size bars. Red for >1 GB, yellow for >100 MB — the heaviest directories jump out instantly, no guesswork needed.
Built-in File Ops
Copy, cut, paste, rename, delete to Recycle Bin or permanently — all with full keyboard shortcuts (Ctrl+C/X/V, Del, F2). No need to switch to Explorer.
Directory Advisor
Automatically identifies common dev caches, AI model directories, and build artifacts. Know what's safe to clean without researching each folder yourself.
Nothing changes on your disk without you knowing
DiskBrain automatically saves a snapshot every time you scan your drive. Come back days or weeks later, pick any two snapshots, and instantly see which directories are responsible for the growth — down to the exact file.
