Question details

The user needs to recover files placed in the local OneDrive folder that were lost because the computer was reinstalled before synchronization could complete.

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Reinstalling a computer shortly after adding new files to the local OneDrive folder, interrupting the upload process.
Observed behavior: Newer files are completely missing after the PC reinstall, and only older, previously synced files appear in the OneDrive account.

Before you start

Before proceeding, confirm your Microsoft account credentials and verify if you temporarily copied the missing files to an external hard drive or USB drive prior to reinstalling your PC.

Solution 1Recommended

Check OneDrive Online and Recycle Bins

Verify if the files managed to upload to the cloud right before the PC was wiped by checking the web portal and recycle bins.

Even if the sync appeared incomplete locally, some files might have successfully reached the OneDrive servers. Checking the web interface is the most direct way to confirm what was actually saved.

Log in to OneDrive Web

Navigate to https://www.office.com/ in your browser, sign in with your Microsoft credentials, and open the OneDrive app.

Search for the Missing Files

Browse through 'My files' to see if any of the newer files were successfully uploaded before the reinstall.

Check the First-Stage Recycle Bin

Click on 'Recycle bin' in the left navigation pane to see if the files were accidentally flagged for deletion during the sync interruption.

Check the Second-Stage Recycle Bin

Scroll to the very bottom of the Recycle bin page and click on 'Second-stage recycle bin' to look for permanently deleted files that can still be recovered.

Download Immediately: If you find your missing files in the web interface, download them directly to your computer to secure a local copy immediately.

Solution 2

Use the OneDrive Restore Feature

Roll back your entire OneDrive to a specific point in time before the PC reinstall occurred.

Solution 3

Contact Microsoft Support for Advanced Recovery

If the files are nowhere to be found, a Microsoft 365 Administrator can request backend recovery assistance.

Frequently Asked Questions

Can I recover files if OneDrive says sync was pending during a PC reset?

If the synchronization was still pending or incomplete when the computer was reset, the actual file data was not successfully uploaded to Microsoft's servers. In this scenario, you cannot recover them from the cloud and will need to rely on physical local backups or professional data recovery software.

Where is the second-stage recycle bin in OneDrive located?

The second-stage recycle bin is found at the very bottom of the standard OneDrive Recycle Bin page on the web portal. It acts as a safety net, holding files that were recently deleted or purged from your main recycle bin.

How long does OneDrive keep deleted or lost files in the recycle bin?

For personal Microsoft accounts, deleted files are retained in the recycle bin for 30 days. For work or school Microsoft 365 accounts, the retention period is typically 93 days, unless the recycle bin exceeds its storage limit and automatically purges older items.
