From Download to Clean Disk in 3 Steps
No technical knowledge required — just install, scan, and clean.
Download & Install
Buy once and get your download link instantly by email. Install takes under 30 seconds on any Windows 10 or 11 (64-bit) PC.
Scan Your C: Drive
Click Scan. First full C: scan time depends on disk size, speed, and files—often a few minutes, but large or busy PCs can take longer.
Clean & Reclaim Space
See the full breakdown. Cleanup actions require your explicit confirmation, and broad dangerous locations are protected — please read actions carefully.
Everything Built In
WhatAteMyDisk gives you a complete picture of your C: drive — then helps you clean it up safely. Scans are local and no data leaves your PC unless you choose to export it (e.g., via the Copy-for-AI workflow, where data only leaves the device if you paste/send it elsewhere).
Category Breakdown
See space used by Windows, apps, user data, browser cache, temp files and recycle bin — all in one clear view.
Largest Folder Finder
Rank your top 200 biggest folders quickly. Spot that one runaway folder hogging all your space.
Guided Cleanup
Temp and cache cleanups are intended to be safe for most users, but some files may be in use and won’t delete until apps are closed. Run as Administrator only if you understand the risk.
Snapshot Comparison
Take snapshots over time and compare them. See exactly what grew between sessions and where new space went.
AI Export Ready
Export your full disk report and paste into ChatGPT for an advisory cleanup plan. AI suggestions are advisory; you must confirm all paths; destructive actions are always intentional.
RAM & Memory View
See your RAM usage, pagefile.sys and hiberfil.sys. No background service; the app only uses resources while it’s open (scanning can be CPU- and disk-intensive).

Common Questions
Everything you need to know about safety, compatibility, and privacy.
Is it safe to use on my PC? +
Yes — WhatAteMyDisk only reads your disk during scanning. Nothing is deleted automatically. Cleanup actions require confirmation, and broad dangerous locations are blocked—but you should still read each action and close apps that may lock files.
Do I need to be a tech expert? +
Not at all. WhatAteMyDisk is built for everyday users. Install, scan, and you’ll see a clear breakdown. Actions are manually confirmed to prevent accidents.
How is this different from free tools? +
WhatAteMyDisk is designed as a modern utility that bundles visual disk scanning with guided, confirmed cleanup, growth snapshots, and AI-powered export analysis in a user-friendly interface.
Will it slow my PC? +
No installed background service. The app only uses resources while it’s open. Scanning can temporarily be CPU- and disk-intensive while the scan runs, but there’s no ongoing background load afterward.
What Windows versions are supported? +
Windows 10 and 11, 64-bit only. We cannot offer refunds if purchased for incompatible systems (Win 7/8/32-bit).
Can I install it on multiple PCs? +
Yes — your license covers personal use and unlimited reinstalls on your own computers. It is non-transferable.
What if it doesn’t work? +
Contact us at support@creatorhex.com within 7 days of purchase. If the issue is due to a technical bug we cannot resolve, we will issue a full refund. Refunds do not apply to purchases on unsupported OS/arch.
