Free up your PC without the guesswork
Point PCMaid at a folder or connect your Windows PC. You get a checkmark list of what is safe to remove and exactly how much space you win back. Everything is backed up and verified before it is deleted.
How does PCMaid work?
- Scan. Choose a folder in Chrome or Edge, or install the small Windows agent for system-wide places a browser cannot reach.
- Tick. Review a list grouped by category with the size of each. Safe items are pre-ticked, everything else waits for you.
- Clean. PCMaid copies, verifies and only then removes. The total space freed is saved to your history.
What can PCMaid clean?
| Category | Tier | What it is |
|---|---|---|
| Windows and app caches | Safe | Temp files, thumbnail cache, crash dumps, update download leftovers, browser caches. Rebuilt automatically. |
| Partial downloads and .tmp files | Safe | Left behind by interrupted downloads and installers. |
| Empty folders | Safe | Folder trees that contain no files at all. |
| Duplicate files | Review | Identical content confirmed with SHA-256. One copy of each group is always kept. |
| Old installers and large unused files | Review | Setup files older than 30 days and large files untouched for 6 months. |
| node_modules and build folders | Review | Recreated with a package install or a build. |
| Documents, photos, desktop, system folders, registry | Never touched | On a never-touch list. PCMaid does not clean the registry. |

Questions people ask
Is PCMaid safe to use?
Yes. Items are sorted into three tiers: safe (rebuilt automatically by the app that owns them), review (needs your checkmark and a verified backup) and advanced (never automatic). Your documents, desktop, downloads, photos and system folders are on a never-touch list.
Does PCMaid upload my file names?
No. The browser scan reads folders locally. Only totals per category, such as 4.5 GB of cache files, are saved to your account. File names and contents never leave your computer.
How does PCMaid find duplicate files?
It compares file sizes first, then a 4 KB fingerprint, then a full SHA-256 hash. Only files with identical content are listed, and one copy of every group is always kept.
Does PCMaid clean the Windows registry?
No, by design. Registry cleaners save almost no space and can break software, so PCMaid leaves the registry alone.
Can PCMaid clean my PC automatically?
Yes. The small Windows agent runs as a scheduled task, scans on a timer and cleans only the safe tier. Review items always wait for your checkmark.
Which browsers are supported for scanning a folder?
Chrome and Edge version 86 or newer, because they provide the File System Access API. The Windows agent works without a browser.
