How to One-Click Clean the C Drive with Tools

Want one-click convenience? Set guardrails before hitting Start.

1. Choose an ad-free portable build with preview; run as admin to avoid install residue.
2. After scan, review the list—whitelist Desktop/Documents/repos immediately.
3. Common whitelist: .gradle, npm-cache, certificate folders, VPN configs, Desktop, Documents, source repos.
4. Select update cache, temp files, browser/WeChat cache; confirm the expected free space.
5. Save the report to D: or cloud for traceability; on work PCs, send to IT.
6. Worried about mistakes? Run “dry-run” to get a list first, then clean for real.

One-click can be safe if setup is solid.

If cleanup fails

• Possibly permissions: run as Administrator.
• Possibly file locks: close browser/WeChat/games and retry.
• Possibly missing whitelist: if something’s gone, restore from backup/Recycle Bin, then add the path to whitelist.

Local tip

In northern winters with low voltage, plug in laptops before one-click—avoid sleeping mid-run.

Fallback

If errors occur, try cleaning only temp dirs first; if still failing, switch to portable build or Safe Mode—usually works.

Make a habit: screenshot the freed-space stats after each run—good reference and proof.
