How to Verify OneDrive Data After a Mover Transfer
Question details
The user needs to verify the completeness and integrity of a OneDrive data transfer using Mover after noticing discrepancies in file counts and storage totals.

- Product
- OneDrive
- Device & OS
- not provided
- Scenario
- Migrating data from an over-quota OneDrive Student account to a OneDrive for Business account using the Mover transfer tool.
- Observed behavior
- The Mover transfer reports show mismatched storage totals and file counts between the source and destination, alongside several terminated transfer requests.
Do not empty or delete any folders in your source OneDrive Student account until you have cross-checked the data. Ensure you have enough local hard drive space available to temporarily hold your downloaded files for verification.
Perform a Local Batch Migration and Verification
Because over-quota cloud accounts can cause direct transfer failures, downloading your files to a local drive ensures you can safely verify and upload them to the new destination.
Cloud-to-cloud synchronization services like Mover can struggle or silently terminate requests when the source account is restricted due to storage limits. A manual local transfer in smaller batches provides absolute control over your files.
Log into your Mover dashboard, navigate to your Migration Manager, and open the detailed transfer logs. Look specifically for 'Failed' or 'Terminated' requests to identify which folders did not migrate successfully.
Open your source OneDrive Student account in a web browser. Select a small group of folders (e.g., 2-5 GB at a time), click 'Download', and save them to a designated folder on your computer's local hard drive.
Right-click the newly downloaded folder on your local drive and select 'Properties'. Compare the 'Size' and 'Contains' (file and folder count) metrics against the source folder properties in the OneDrive web interface to ensure everything downloaded.
Sign into your new OneDrive for Business account. Drag and drop the verified local folders into the browser window to upload them. Repeat this batch process until all missing data is securely transferred.

Use Rclone for Advanced File Verification
For users comfortable with command-line tools, rclone can precisely scan, compare, and sync missing data between two cloud storage points without fully downloading everything.
Easily Access Your Migrated OneDrive Files with WPS Office
After successfully verifying and moving your data to your new OneDrive account, you need a reliable way to open and edit your documents. WPS Office is a powerful, lightweight suite that integrates directly with cloud storage platforms.
- 1. Install WPS Office: Download and install WPS Office from the official website on your PC or Mac.
- 2. Connect to OneDrive: Open WPS Office, navigate to 'Open' in the left sidebar, click on 'Add Cloud Storage', and log in with your new OneDrive for Business credentials.
- 3. Edit your documents: Browse your OneDrive folders directly within the WPS interface and click on any document, spreadsheet, or presentation to begin editing instantly.

Frequently Asked Questions
Why did my Mover transfer terminate before finishing?
Transfers often terminate if the source account (like a Student OneDrive) is over its storage limit. This over-quota status can trigger Microsoft to throttle or restrict API read requests, causing the migration tool to time out or skip files.
What is the safest way to migrate files from an over-quota OneDrive account?
The safest method is to bypass cloud-to-cloud sync tools and manually download the files in small batches to a local hard drive, verify their sizes and counts, and then upload them directly to the new account.
How do I check for missing files without downloading everything again?
You can check the Mover transfer logs for detailed error reports. Alternatively, you can use the command-line tool rclone with the 'rclone check' command to securely compare the contents of both cloud drives and list missing files.
