Windows slowly collects files it no longer needs. A full disk stops Windows updates, breaks game servers and can even stop the server starting. Free up disk space clears the clutter safely.
Clean up
- Open Fix my server and find Free up disk space. You'll also see Free up space buttons on the "C: is almost full" warnings.
- Click Clean up now.
- Choose any extras (see below), then click Clean up.
The card shows the progress. When it's done, it tells you how much space was freed and how much C: now has.
What it deletes
- Temporary files
- Old Windows Update downloads
- Crash reports and memory dumps
- Old Windows and HTN logs
Only files older than a few days are deleted, so nothing that's in use is touched.
The two extras
- Also empty the Recycle Bin. Files in it can't be restored afterwards.
- Deep clean. This removes files left behind by old Windows updates. It frees the most space, but takes 10 to 30 minutes and slows the server while it runs. Best done at a quiet time.
💡
Safe by design: cleanup never touches your game servers, your backups or your own files.
Still short on space?
- Delete old backups in File backups, after copying any you want to keep to your own PC.
- If your disk was upgraded, check Fix my server for Extend C:.
- If you've simply outgrown it, upgrade your plan for a bigger disk.
