Disk Cleanup Helper is a free, open-source Windows 10/11 app that frees up disk space safely and keeps an eye on your disks. Nothing is deleted until you select it and confirm.
The Clean up tab finds browser and app caches, temp files, old Windows update files and other leftovers. Every item explains what you keep and what you lose. Clean up never touches your documents, photos, music, videos, desktop or downloads folders, and browser caches keep your passwords, bookmarks and logins.
Analyze disk shows the biggest folders and files on your drives; you can move the files you pick to the Recycle Bin or delete them permanently. Disk health shows whether each disk is healthy, with a live temperature, history charts and the full SMART data. There is also a disk speed test, live disk activity and a device details page.
It is one small file that runs without installing (you can install it from the About tab if you want) and uses the .NET Framework built into Windows. Light and dark themes, 18 languages. No account, no ads, no tracking: the only connection it makes is a daily update check on GitHub, which you can turn off.
