  • The 64-bit OneDrive sync client for Windows is now available in public preview.
  • The current OneDrive sync client for Windows is only 32-bit.
  • The 64-bit version is better for syncing large files or a large number of files.

Microsoft is testing an improved version of the OneDrive sync client for Windows. The new version is 64-bit, as opposed to the current version that's only 32-bit. The 64-bit OneDrive sync client for Windows is available now in public preview.

64-bit OneDrive sync client for Windows will help sync larger files and will handle large numbers of files better than the current 32-bit version.

Microsoft explains the benefits of the 64-bit version in a Tech Community post:

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).

The 64-bit OneDrive sync client for Windows is only available in public preview for AMD64 devices, meaning that people with ARM64 devices have to stick with the 32-bit version.

The new version of the OneDrive sync client is rolling out in public preview now, and it should be generally available by the end of the month, according to Petri.
