Question details

The user needs to recover and sync files in the Desktop and Documents folders that became inaccessible following a system crash.

Product: Microsoft OneDrive
Device & OS: Windows
Scenario: Attempting to access, open, or back up local files in the OneDrive folder after a SYSTEM_THREAD_EXCEPTION_NOT_HANDLED error interrupted the synchronization process.
Observed behavior: The unsynchronized files cannot be opened, copied to an external drive, and do not appear in the web version of OneDrive.

Before you start

Ensure your computer is in a stable state by temporarily booting into Safe Mode or addressing the underlying blue-screen error before attempting file recovery to prevent further data corruption.

Solution 1Recommended

Reset the OneDrive Application

Resetting OneDrive can resolve sync issues caused by unexpected system crashes without losing any of your existing data.

A sudden system failure can leave the OneDrive sync client in an error state, locking files and preventing them from opening or syncing properly. Resetting forces the app to re-evaluate all files.

Open the Run dialog box

Press the Windows key + R on your keyboard simultaneously to open the Run window.

Execute the reset command

Type '%localappdata%\Microsoft\OneDrive\onedrive.exe /reset' into the dialog box and click OK.

Restart OneDrive

If the OneDrive cloud icon does not reappear in your system tray after a few minutes, open the Start menu, search for 'OneDrive', and click on the app to launch it manually.

Data Safety: This command forces a full sync, which can reconnect unsynced files. It will not delete your personal files.

Solution 2

Contact Microsoft OneDrive Support

If resetting the application does not unlock the files, official support may be required to recover heavily corrupted unsynced data.

Solution 3

Troubleshoot the Blue Screen Error

Fix the underlying SYSTEM_THREAD_EXCEPTION_NOT_HANDLED error to restore system stability and prevent future file lockups.

Frequently Asked Questions

Why are my OneDrive files unopenable after a blue screen?

When a blue screen like SYSTEM_THREAD_EXCEPTION_NOT_HANDLED occurs, the system forcefully shuts down. If OneDrive was in the middle of syncing or modifying a file, the data can become locked or corrupted, leaving the local file unreadable.

Will resetting OneDrive delete my local files?

No, resetting the OneDrive application only resets the synchronization settings and forces a full system check. It does not delete any of your personal files, folders, or data.

Can I recover unsynced files from the OneDrive website?

If the files never successfully finished syncing to the cloud before the system crash, they will not be visible or recoverable from OneDrive on the web. You must attempt to repair the local files or the sync application first.

How do I fix the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED error?

This error is typically caused by outdated, incompatible, or faulty device drivers. You can often fix it by booting into Safe Mode, updating your graphics and network drivers, and running a System File Checker (SFC) scan.
