Hi ted sirrine,
Welcome to the Microsoft Q&A forum.
When OneDrive is set to sync special folders like Desktop, Documents, or Pictures, it actively keeps those files aligned between your PC and the cloud. In some situations, such as when sign‑in credentials are refreshed or sync is interrupted, OneDrive may create “conflict copies” instead of matching files one‑to‑one. This can look like unexpected duplicates and may increase storage usage.
Here are some quick steps that you can try to stop duplicate files:
1, Refresh OneDrive sign‑in credentials
- Select Start, search for Credential Manager
- Open Windows Credentials
- Remove entries named OneDrive Cached Credential
- Restart OneDrive
2, Review Desktop backup settings
- Select the OneDrive cloud icon > Settings
- Go to Sync and back up
- Turn off backup for Desktop (optional)
3, Use Files On‑Demand to reduce local activity
- In OneDrive Settings, keep Files On‑Demand enabled
- Right‑click duplicated folders and select Free up space
4, Clean up safely
- Delete duplicate copies (files with PC name or “(1)”)
- Empty the OneDrive Recycle Bin to reclaim storage
