ZMasterClean shows you exactly what is eating your disk, clears the junk that is genuinely safe to delete, and moves installed apps to another drive — no reinstall, no broken shortcuts, no registry surgery.
Windows ships with a 120 GB system partition, then quietly fills it from every direction. By the time the low-disk warning appears, the damage is already structural.
Games, IDEs, Creative Suite, Docker images. Most installers never ask, and many refuse to relocate after the fact — so 500 GB of data ends up on a 120 GB partition.
Windows Update keeps old build packages. Browsers keep every favicon. Hibernation reserves RAM-sized files. None of it is visible in File Explorer.
Partition resizing, drive cloning, "registry cleaners". One wrong click and you are reinstalling Windows on a Sunday. Most people just live with 2 GB of free space.
No "PC optimizer" nonsense. ZMasterClean does four very specific things, and shows its work before it touches anything.
A single scan maps every folder on the drive and renders it as a treemap, sized by real occupied bytes. No guessing which folder is the culprit — the big blocks are the answer.
ZMasterClean groups removable data into categories you can inspect one by one, with the exact path and impact of each item. Nothing is deleted until you tick it and confirm.
This is the feature you will actually pay for. ZMasterClean relocates a program's files to a target drive and rewrites the links Windows depends on, so the app keeps launching from the Start menu exactly as before.
A health check that reads what Windows will not put in one place: partition layout, free space trend, drive health, and the specific risks that come with a nearly-full system volume.
You can. Here is what that costs, honestly.
| Task | Doing it manually | ZMasterClean |
|---|---|---|
| Find what is using the space | Explorer properties, folder by folder | One scan, visual treemap |
| Clear update cache | Stop services, delete folders by hand | One checkbox |
| Move an app off C: | Uninstall → reinstall elsewhere → lose settings | Relocated in place, settings intact |
| Fix a broken shortcut afterwards | Hunt through the registry | Handled automatically |
| Undo a mistake | Restore point, if you remembered one | Automatic rollback on failed verification |
| Time required | 1–3 hours, high risk | About 3 minutes, reversible |

It is safer than uninstalling and reinstalling, because your settings, plugins and license state stay untouched. ZMasterClean copies the program folder to the target drive, updates the registry entries and shortcuts that point at it, then launches the app to verify. If the verification fails, it restores the original location automatically and leaves C: exactly as it was.
We deliberately do not offer to move Windows itself, drivers, or anything inside C:\Windows. Those are the cases that break machines.
The installer is digitally signed, which removes the "unknown publisher" warning. Some heuristic engines still flag any tool that touches the registry — if that happens, please send us the detection name and we will submit a false-positive report to the vendor. A VirusTotal link for every release is published on the download page.
No. Scanning, cleaning and migration run entirely offline. The only network call the app ever makes is a license check when you activate Pro, which sends the key and a hashed machine ID — never a file name, never a path, never a usage profile. See the Privacy Policy for the exact payload.
Your license is perpetual: the version you bought keeps working forever. The 12 months only covers new releases. When it lapses you can keep using what you have, or renew at a discount if you want newer Windows builds supported. Nothing stops working.
Yes. Deactivate on the old machine from the About screen, then activate on the new one. If the old machine is dead and you cannot deactivate, email us with your order number and we reset it for you — usually within one business day.
Windows 10 (1809 and later) and Windows 11, 64-bit only. Windows 7 and 8.1 are not supported. Server editions work but are not officially tested; the Studio plan is the right fit if you need it on a server.
Email 350400341@qq.com within 30 days of purchase with your order number. We refund in full through the original payment method. No reason required, no survey, no "are you sure" loop.
Download it, run one scan. If it does not find at least 10 GB you can safely remove, close it and forget we exist.
