CDX Disk Manager
Reclaim disk space safely, see where storage goes and keep Windows fast. A free Windows 10 and 11 utility from Webline Technologies, distributed through the Microsoft Store.
What it does.
Deep cleanup
140 curated rules for Windows, browsers, apps, developer tools and AI model caches. Each rule explains what the data is and what happens after cleanup.
Space analyzer
Every folder drawn to scale as a treemap or sunburst, with drill-down into any drive.
Large files
The biggest files on each drive, classified by type and sorted by size, age or last use.
Duplicates
Files with identical content, found by comparing bytes rather than names. One copy in every group is always kept.
Uninstall apps
Desktop and Store apps with their sizes, plus the folders and registry keys uninstallers leave behind.
Startup items
Everything that launches at sign-in, with an impact estimate and a switch to turn each one off.
Privacy cleanup
Browser history and cookies, recent items, jump lists and Explorer histories.
Maintenance
One-click fixes for DNS, icon and thumbnail caches, Windows Search, audio, networking and Windows Update.
Resources and history
Live CPU, GPU, memory, disk and network use, and a history of every operation with one-click restore.
Safety
Built so nothing is lost by accident.
Scans only read. Nothing is removed until you review the list and confirm it.
- Removed files go to the Recycle Bin by default, and History restores a whole cleanup in one click.
- Cloud placeholder files from OneDrive and similar services are never downloaded, counted or deleted.
- Drive roots, profile roots and your documents can never be cleanup targets.
- Every Windows setting the app changes is read back and can be reverted.
Administrator rights
Standard user by default.
CDX Disk Manager starts as a standard user. Scanning, cleaning your own profile, the analyzer, duplicates, large files and most settings never need administrator rights.
A few actions change the whole PC, so Windows only allows them for an administrator. They are marked in the app, and they run only after you click them and approve the normal Windows User Account Control prompt:
- Cleaning machine-wide locations: the Windows Update download cache, Delivery Optimization files, Windows.old, memory dumps and the system temp folder.
- Restarting Windows services: Windows Search, Windows Audio and the Print Spooler.
- Network and system repairs: resetting Winsock and TCP/IP, flushing DNS, and running DISM and System File Checker.
- Turning off startup entries that apply to every user (HKEY_LOCAL_MACHINE and the common Startup folder).
If you decline the prompt, nothing changes and the rest of the app keeps working.

Common questions.
Is CDX Disk Manager free?
Yes. Version 1.0 is free, with no ads, no account and no upsell screens.
Does it send my data anywhere?
No. The app has no telemetry, analytics or crash reporting and makes no network requests of its own. Scan results stay on your PC.
Why does it sometimes ask for administrator rights?
Only when you choose an action that changes the whole PC, such as clearing the Windows Update download cache or running System File Checker. Windows shows its normal User Account Control prompt and you can decline. Everything else runs as a standard user.
Can I undo a cleanup?
Yes. Files go to the Recycle Bin by default, and the History page restores a whole cleanup in one click.
How do I uninstall it?
Right-click CDX Disk Manager in the Start menu and choose Uninstall, or open Settings, Apps, Installed apps. The Microsoft Store package removes itself completely.
