See what is using the drive
- Open Settings, System, then Storage to review categories.
- Large applications, videos, Downloads, and old user profiles usually matter more than tiny temporary files.
- Confirm important folders are backed up before moving or deleting them.
Free space safely
- Use Windows Storage recommendations or Disk Cleanup for temporary and update files.
- Uninstall unused programs through Settings instead of deleting program folders.
- Move archived photos and videos to a verified backup or external drive.
Avoid risky shortcuts
- Do not manually delete Windows, Program Files, or hidden system folders.
- Do not trust cleanup utilities that report thousands of alarming registry errors.
- Empty the Recycle Bin only after confirming nothing important is inside.
