Microsoft is now offering a preview of the 64-bit version of OneDrive for Windows for anyone who wishes to test this long-overdue update.
“We know this has been a long-awaited and highly requested feature, and we’re thrilled to make it available for early access,” Microsoft’s Ankita Kirti writes. “You can now download the 64-bit version for use with OneDrive work, school, and home accounts.”
So what does 64-bits get you over the current 32-bit version? According to Microsoft, it’s useful for anyone who needs to access large files since 64-bit versions of Windows—and now OneDrive—can access more system resources than 32-bit versions.
The 64-bit version of OneDrive does require a 64-bit version of Windows, of course, but it doesn’t work, at least for now, on Windows 10 on ARM. I assume that you will automatically get the right version, 32-bit or 64-bit, in the future.
