Question details

The user needs to find an alternative method to transfer a large 93 GB file between two OneDrive accounts.

How to Transfer Large Files Between OneDrive Accounts Without Mover

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Migrating extremely large files across different OneDrive or OneDrive for Business accounts.
Observed behavior: The Mover migration tool blocks the transfer because the file exceeds its maximum 15 GB file-size limit.

Before you start

Ensure your computer has sufficient local storage space to accommodate the 93 GB file and verify that you are connected to a stable, high-speed internet network to handle the extensive upload and download process.

Solution 1Recommended

Use the Local OneDrive Sync Client

Use the desktop OneDrive sync client to act as a bridge between the two accounts by dragging and dropping the file from one folder to another.

This is the most straightforward method for moving files between two OneDrive for Business accounts. It bypasses Mover's 15 GB limitation by utilizing your computer's local file management system.

Because this method requires downloading the file to your computer first and then uploading it to the new account, it will consume significant local disk space and network bandwidth.

Add Both Accounts to OneDrive

Click the OneDrive cloud icon in your Windows taskbar, select 'Settings', navigate to the 'Account' tab, and click 'Add an account' to link your second OneDrive account.

Open File Explorer

Open Windows File Explorer (or Finder on Mac) and locate the synchronization folders for both your source and destination OneDrive accounts in the navigation pane.

Move the Large File

Find the 93 GB file in the source OneDrive folder, then drag and drop (or cut and paste) it into the destination OneDrive folder.

Wait for Synchronization

Keep your computer powered on and connected to the internet while the OneDrive sync client processes the upload to the new cloud account.

Time Intensive Process: Transferring a 93 GB file locally will likely take several hours, depending entirely on your internet connection's upload and download speeds.

Solution 2

Automate the Transfer using Microsoft Power Automate

Create a cloud-to-cloud flow using Power Automate to transfer files without downloading them to your local hard drive.

Frequently Asked Questions

Why does the Mover migration tool restrict my file transfer?

Mover has a strict file-size limit of 15 GB per file. Any individual file exceeding this size cannot be processed by the Mover platform and requires a manual or alternative migration method.

Can I transfer files between OneDrive accounts without downloading them locally?

Yes, to achieve a cloud-to-cloud transfer without local downloading, you must use a supported third-party cloud migration tool or configure a custom script using Microsoft Power Automate.

How long will it take to sync a 93 GB file via the OneDrive desktop client?

The duration depends entirely on your internet connection. Since the file must be downloaded locally and then uploaded to the new account, a 93 GB file can take anywhere from a few hours to an entire day on a standard broadband connection.
