Hello microsoft user_270,
Thank you for asking a question in the Microsoft Community!
Based on your question, I understand that you want to know if Onedrive files are lost after resetting your Windows computer to factory settings. My answer to you is that Onedrive files are not lost after resetting your computer because Onedrive files are synchronized to the cloud with the associated Microsoft account. You just need to sign in your previous Microsoft account in Onedrive after resetting your computer, your files will be automatically synchronized to your desktop, you don't need to worry about file loss. If you are still worried about losing your files, it is recommended that you backup them to your removable disk.
