OneDrive for Windows 10 just got better at syncing large files
OneDrive on Windows just got a performance boost for syncing large files.
What you need to know
- The 64-bit version of OneDrive is rolling out to Windows 10 PCs.
- It should bring better performance for syncing large files than its 32-bit counterpart.
- Microsoft began testing the 64-bit version of OneDrive with Windows Insiders in April 2021.
Microsoft recently started rolling out the 64-bit version of OneDrive to Windows 10 PCs. The new version of the cloud syncing app should handle large files better than the 32-bit version available previously. Jason Moore, head of product for OneDrive and Microsoft Lists, shared news of the rollout on Twitter.

After switching to the 64-bit version of OneDrive, syncing large files and syncing large numbers of files should be faster. In terms of user interface and design, the app appears identical to the 32-bit version of OneDrive.
Microsoft explains the benefits of the 64-bit version of OneDrive in a Tech Community post from when it first rolled out to Insiders:
The 64-bit version is the right choice if you plan to use large files, if you have a lot of files, and if you have a computer that's running a 64-bit version of Windows. Computers running 64-bit versions of Windows generally have more resources—such as processing power and memory—than their 32-bit predecessors. Also, 64-bit applications can access more memory than 32-bit applications (up to 18.4 million Petabytes).
At this time, there isn't an ARM64 version of the 64-bit version of OneDrive.
