To free up space on your computer’s hard drive, you can consider deleting:

1. Temporary files and cached data
2. Old downloads you no longer need
3. Duplicate files
4. Unused applications
5. Old backups or system restore points
6. Large files you don’t use (e.g., old videos or photos)
7. Browser cache and history
8. Recycle Bin contents

Before deleting anything, ensure you don’t need the files. If you’d like more details on how to safely remove these items or want information on additional ways to free up space, let me know.
