- Device & OS
- Windows
- Scenario
- Recovering and resuming an interrupted file transfer to Microsoft OneDrive after an unexpected system shutdown or power failure.
- Observed behavior
- The file upload process stopped midway due to the power outage, leaving files partially uploaded or unsynced in the destination folder.
Verify that your internet connection is stable and ensure your PC has fully restarted. Check the original source folder on your local drive to confirm the files are still intact before attempting the upload again.
Resume Upload via the OneDrive Website
Using the OneDrive web portal is the most direct method to manually ensure your specific files or folders are completely uploaded without relying on background sync.
If your system lost power during a transfer, the web interface allows you to selectively re-upload the missing items and resolve any potential conflicts immediately.
Open your preferred web browser, navigate to the official OneDrive website, and log in with your Microsoft account credentials.
Browse through your OneDrive directory to find the specific folder where the interrupted files were originally being uploaded.
Click on the 'Upload' button at the top of the interface, then choose either 'Files' or 'Folder' depending on what you need to transfer.
Select the required files or folders from your local device to restart the upload process. If prompted about duplicate files, choose to 'Replace' to ensure you have the fully uploaded version.
Use the OneDrive Desktop Sync App
If you have the OneDrive sync application installed on Windows, you can utilize File Explorer to drag and drop files to resume the transfer.

Frequently Asked Questions
Will OneDrive duplicate my files if I re-upload them after an interruption?
Generally, no. If OneDrive detects a file with the same name during a manual upload, it will usually prompt you to either 'Replace' the file or 'Keep both'. Since the original upload was interrupted, it is recommended to select 'Replace' to ensure the file is intact.
What happens to my local files if the power fails during a 'cut and paste' operation?
If a cut-and-paste transfer is interrupted by a power failure, the operating system may leave the original files in the source folder until the transfer is completely verified. However, in cases of a sudden crash, data corruption is possible. Always check your local source folder first to confirm the original files are unharmed.
Does the OneDrive desktop app resume syncing automatically when the computer turns back on?
Yes, once Windows restarts and the OneDrive sync app launches, it will automatically scan the OneDrive directory for changes. Any files that were successfully placed in the local OneDrive folder before the crash will automatically resume syncing to the cloud.
How can I tell which files failed to upload during the power outage?
In File Explorer, check the status icons next to the files in your OneDrive folder. Files with a red 'X' or missing a green checkmark failed to sync. Online, you can compare the contents of your cloud folder with your local source folder to identify missing items.
