Why is OneDrive Reporting Full Storage When I Have No Files?

Hey, OneDrive usually backs up certain files on your computer automatically. Have you looked for any check marks on your folders? That might indicate it's trying to sync something. You could also consider uninstalling OneDrive as a possible fix. Additionally, if you're signed in on multiple devices, check if your phone is contributing to the storage since that's often where photos and videos take up space. You can also check your storage usage by logging into onedrive.com with your account. Look for the storage quota display on the bottom left of the UI for more details.

You might want to ignore the suggestion about metrics for individual users since that’s not usually available. OneDrive can link across devices, so it's important to check your phone as it could be where the most storage is used, especially from photos or videos. If you can share screenshots of your storage usage, that would help pinpoint the problem. Keep an eye on new auto-backup features that Microsoft added recently; they now back up some folders under Appdata which could be taking up space without you knowing.
