Microsoft has announced the public preview of the 64-bit version OneDrive app for Windows.
Windows 10 users can now download the 64-bit version for use with OneDrive work, school, and home accounts.
If your machine is running a 64-bit version of Windows, you can try to move from the 32-bit client to 64-bit ensuring 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 : If you have a 64-bit operating system with an x64-based processor, you can choose to install either the 32-bit or 64-bit OneDrive.
For ARM64 devices, you should continue to use the 32-bit OneDrive.
