How to Relink OneDrive to an Existing Folder on Windows

Question details

The user needs to reconnect OneDrive to an existing folder after a Windows reinstallation and system language change interrupted the synchronization.

Product: OneDrive
Device & OS: Windows
Scenario: Reinstalling Windows and switching the system language from Chinese to English caused the existing OneDrive directory to be renamed, breaking the connection.
Observed behavior: OneDrive fails to reconnect to the preserved folders. Attempts to rename or delete the folders result in a "Cloud file provider is not running" error, and system folders like Documents and Music are stuck due to Known Folder Backup.

Before you start

Ensure you are signed in with the correct Microsoft account associated with your original OneDrive files. Temporarily pause any active third-party antivirus software that might be blocking cloud synchronization processes.

Solution 1Recommended

Unlink and Relink OneDrive to Your Existing Folder

This process disconnects your current broken OneDrive setup and lets you manually choose your previously preserved folder to resume syncing without redownloading all files.

By unlinking your PC and relinking it directly to the preserved folder, OneDrive will scan the existing data and merge it with the cloud, resolving path inconsistencies caused by the system language change.

Open OneDrive Settings

Click the OneDrive cloud icon located in the Windows system tray (taskbar), click the gear icon, and select Settings.

Unlink this PC

Navigate to the Account tab in the settings window and click the "Unlink this PC" link to disconnect your account.

Sign back in

The OneDrive setup screen will automatically appear. Enter your Microsoft account email and password to sign back in.

Select your existing folder

When prompted with the "Your OneDrive folder" screen, click "Change location" and select the existing, preserved OneDrive folder on your hard drive.

Confirm folder usage

A warning will appear stating that files already exist in this folder. Click "Use this folder" and proceed to complete the setup wizard.

Wait for Synchronization: Do not delete, move, or rename any files until OneDrive has finished scanning and verifying the existing local files against the cloud.

Solution 2

Disable Known Folder Backup for Protected Folders

If you cannot rename or delete local folders like Documents or Music, Windows might still consider them protected by OneDrive's PC Folder Backup feature.

Solution 3

Reset the OneDrive Application

Resetting OneDrive forces the application to clear its configuration cache, which can resolve underlying process failures causing the "Cloud file provider is not running" error.

Frequently Asked Questions

Why does OneDrive show a 'Cloud file provider is not running' error?

This error usually happens when the core OneDrive background sync processes or related Windows cloud services are unexpectedly stopped or corrupted. This is common after major system updates, reinstallations, or changing the core Windows system language. Resetting the OneDrive app typically resolves this.

Will relinking an existing OneDrive folder create duplicate files?

No, as long as you specifically choose 'Use this folder' when prompted during the initial sign-in setup. OneDrive is designed to scan the existing local files and merge them with the cloud directory. It will only download missing files or upload changes, rather than duplicating the entire folder contents.

Can changing the Windows display language break OneDrive synchronization?

Simply changing the display language usually does not break OneDrive. However, if the user folder paths (such as C:\Users\[Username]\OneDrive) were localized in the previous language and you performed a system reinstall or deep language pack change, the folder path discrepancy can break the synchronization connection.

How do I recover files if my Documents folder is empty after unlinking OneDrive?

If Known Folder Backup was actively managing your Documents folder before you unlinked your account, your files are likely still safely stored in the OneDrive cloud directory. Open the primary OneDrive folder via File Explorer, locate the backed-up Documents folder inside, and copy your files back to your local C: drive.
