We’re excited to announce that the 64-bit OneDrive sync client for Windows is now available as a public preview!
We know this has been a long awaited and highly requested feature, and we're thrilled to make it available for early access. You can now download the 64-bit version for use with OneDrive work, school, and home accounts.
To move from the 32-bit to 64-bit (or vice versa) you'll need to make sure the OneDrive version you install is the same version as you currently have, or newer. For more information, see What version of OneDrive am I using?
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).
Note: The OneDrive 64-bit version is only for AMD64 devices (for ARM64 devices, you should continue to use the 32-bit OneDrive).
For instructions on installing the 64-bit client see Choose between the 64-bit and 32-bit version of OneDrive.
We continue to evolve OneDrive as a place to access, share, and collaborate on all your files in Office 365, keeping them protected and readily accessible on all your devices, anywhere.
You can stay up-to-date on all things via the OneDrive Blog and the OneDrive release notes.

Thanks for your time reading all about OneDrive,
OneDrive | Microsoft
