How to Fix the 'File is Open by Another User' Error in OneDrive

Product: OneDrive
Device & OS: not provided
Scenario: Saving changes to a file stored in a synced OneDrive folder.
Observed behavior: OneDrive blocks saving, producing an error that the file is open elsewhere even when no other devices are connected. The issue creates network errors and generates duplicate files with suffixes like '(2)' or '(4)'.

Before you start

Before beginning the troubleshooting steps, save a copy of your document to a local folder outside of OneDrive (such as your Desktop) to prevent any accidental data loss while resetting the synchronization.

Solution 1Recommended

Restart OneDrive and Verify Web Permissions

A quick restart clears background ghost processes that may be falsely locking the file, while checking web permissions ensures your account has the correct access rights.

Often, 'file in use' errors occur because a previous editing session did not close properly in the background, leaving a lock on the file. Restarting the client and checking the web interface can clear this state.

Quit the OneDrive application

Right-click the OneDrive cloud icon in your system tray or menu bar, select 'Help & Settings' (the gear icon), and click 'Quit OneDrive'.

Restart your device

Reboot your computer completely to ensure any hidden processes that might be holding the file open are terminated.

Check file permissions on OneDrive Web

Log into the OneDrive website via your browser. Locate the problematic file, select it, and attempt to open it in the web editor to verify that it is not locked by another co-authoring session.

Restart OneDrive and Verify Web Permissions

Web Editing Test: If the file can be opened and saved successfully on the OneDrive website, the issue is strictly related to your local desktop client synchronization.

Solution 2

Clear OneDrive App Data and Resolve Duplicate Files

Sync conflicts often generate duplicate copies of your files that interfere with the original document's ability to save.

Frequently Asked Questions

Why does OneDrive say my file is in use when it's closed?

This usually happens when a background process on your computer fails to release the file lock after you close the document, or if there is a delay in syncing your previous editing session to the cloud.

How do I stop OneDrive from creating duplicate files with numbers?

Numbered suffixes like '(2)' or '(4)' appear when OneDrive detects a version conflict. To prevent this, always ensure your internet connection is stable and allow the OneDrive cloud icon to display a 'Sync Complete' status before turning off your computer or disconnecting from the network.

Can I edit my files offline to bypass this error?

Yes. You can copy the problematic file from your OneDrive folder to a strictly local folder (like your Desktop), edit and save it there, and then copy it back into the OneDrive folder once your synchronization issues are resolved.
