How to Remove Duplicate OneDrive Files After Reconnecting a PC
Question details
The user needs to know how to safely remove duplicate files (often named with '- Copy') that are generated by OneDrive after relinking an account following a system crash or Windows profile change.
- Product
- Microsoft OneDrive
- Device & OS
- Windows
- Scenario
- Relinking or reconfiguring OneDrive on a PC after a system crash, reinstalling Microsoft 365, or setting up a new Windows user profile.
- Observed behavior
- OneDrive creates a new local folder and uploads duplicate copies of files with '- Copy' appended to their names instead of syncing seamlessly with the existing local files.
Before deleting any duplicate files, immediately pause OneDrive synchronization to prevent accidental data loss from mirroring to the cloud. Additionally, verify that your primary local drive has enough free storage space.
Compare and Safely Remove Duplicate Files
Pause synchronization to carefully compare your local files with the online OneDrive directory, ensuring you only delete unnecessary duplicates while restoring your intended folder structure.
When you create a new Windows user profile or reinstall Microsoft 365, OneDrive often defaults to configuring a new folder on the C: drive. If your original files were stored elsewhere (like a D: drive partition), this can cause the syncing engine to duplicate files rather than merging them.
Click the OneDrive cloud icon in your Windows taskbar, select the Help & Settings gear icon, and click 'Pause syncing' to halt all background uploads and downloads.
Open your local OneDrive folder via File Explorer and open OneDrive online in your web browser. Carefully compare the folder structures to identify which files are the originals and which are the '- Copy' duplicates.
Check whether your intended sync location is an internal drive or a partition (such as the D: drive) and ensure that your current default C: drive has enough free space if OneDrive defaulted back to it.
Restore or move the correct original files to your preferred folder structure first. Once you are certain the original data is intact, carefully delete the duplicate files labeled with '- Copy'.
Only after confirming that your complete local data set is correctly organized, reconfigure OneDrive to your intended location (if needed) and resume synchronization from the taskbar menu.
Avoid Syncing Headaches with WPS Office and WPS Cloud

- 3. Edit Existing Microsoft Files: Open your existing Word, Excel, and PowerPoint files directly in WPS Office with zero formatting loss.
- 4. Save Without Duplicates: Use the integrated auto-save feature to back up your progress directly to WPS Cloud, avoiding complex desktop folder syncing errors.
Frequently Asked Questions
Why does OneDrive append '- Copy' to my files?
This happens when OneDrive detects a conflict between a local file and a cloud file, which is common after a PC reconnection, profile change, or offline editing. To prevent data loss, it saves both versions and renames the newer or conflicting one with '- Copy'.
Will I lose my files if I unlink or reinstall OneDrive?
No. Unlinking or reinstalling the OneDrive desktop app does not delete your files. Your data remains safe in your cloud storage and your existing local folders. However, you will need to reconfigure your sync preferences when you sign back in.
How can I change my default OneDrive folder to a different drive?
Go to OneDrive settings and choose 'Unlink this PC'. Sign back in, and when you reach the 'Your OneDrive folder is here' screen during the setup process, click 'Change location' to select a folder on a different drive or partition (such as your D: drive).
