Seeing duplicate "Peter - Personal" OneDrive folders in Windows Explorer is a common issue that can arise after system migrations, re-linking accounts, or registry glitches. This problem not only clutters your file system but can also lead to confusion when managing files. Fortunately, there are several proven methods to resolve this issue and restore order to your OneDrive setup.

Understanding the Cause of Duplicate OneDrive Folders

Duplicate OneDrive folders typically appear due to:

  • Account Re-linking: When you unlink and relink your Microsoft account, Windows may create a new folder structure without removing the old one.
  • Registry Errors: Corrupted or outdated registry entries can cause Windows Explorer to display duplicate folders.
  • System Migrations: Moving to a new PC or reinstalling Windows can sometimes trigger folder duplication.
  • Sync Conflicts: OneDrive might create a duplicate folder if it encounters sync conflicts during file transfers.

One of the simplest solutions is to unlink and relink your OneDrive account:

  1. Open OneDrive Settings: Right-click the OneDrive icon in the system tray and select Settings.
  2. Unlink Account: Go to the Account tab and click Unlink this PC.
  3. Restart Your Computer: This ensures all processes are cleared.
  4. Relink OneDrive: Sign back into OneDrive with your Microsoft account.

This method often resolves the issue by forcing Windows to rebuild the folder structure correctly.

Method 2: Reset OneDrive

If unlinking doesn’t work, try resetting OneDrive:

  1. Close OneDrive: Right-click the OneDrive icon and select Close OneDrive.
  2. Open Run Dialog: Press Win + R, type %localappdata%\Microsoft\OneDrive\onedrive.exe /reset, and press Enter.
  3. Restart OneDrive: Relaunch OneDrive from the Start menu.

This resets OneDrive’s configuration files, which can eliminate duplicate folders.

Method 3: Clean Up Registry Entries

Warning: Editing the registry can be risky. Back up your registry before proceeding.

  1. Open Registry Editor: Press Win + R, type regedit, and press Enter.
  2. Navigate to OneDrive Keys: Go to HKEY_CURRENT_USER\Software\Microsoft\OneDrive.
  3. Delete Problematic Keys: Look for duplicate entries related to your account and delete them.
  4. Restart Your PC: This ensures changes take effect.

Method 4: Reinstall OneDrive

If the issue persists, a clean reinstall may be necessary:

  1. Uninstall OneDrive: Go to Settings > Apps > Apps & features, find Microsoft OneDrive, and select Uninstall.
  2. Download OneDrive: Get the latest version from Microsoft’s official site.
  3. Reinstall and Sign In: Install OneDrive and log in with your Microsoft account.

Preventing Future Duplicates

To avoid this issue in the future:

  • Regularly Update OneDrive: Ensure you’re using the latest version.
  • Avoid Frequent Account Relinking: Only unlink and relink your account when necessary.
  • Monitor Sync Conflicts: Resolve sync issues promptly to prevent folder duplication.

When to Contact Microsoft Support

If none of the above methods work, consider reaching out to Microsoft Support. Persistent duplicates could indicate a deeper system issue that requires professional assistance.

By following these steps, you can eliminate duplicate OneDrive folders and maintain a clean, organized file system. Remember to back up important files before making significant changes to your system.
