Unable to open content synced in a OneDrive folder on an external drive

Unable to open content synced in a OneDrive folder on an external drive

If you have installed the Fall 2017 Creators Update for Windows 10 and you sync OneDrive files to an external drive, you may be unable to open your OneDrive files if you move the external drive to a computer running an operating system older than Fall 2017 Creators Update for Windows 10.

You may receive an error: “The file cannot be accessed by the system." 

Workarounds

The following workarounds are available: 

  • Sign in to onedrive.com with the account that you're having trouble with and download your files.

    Tip: To get to your OneDrive online from your desktop, you can also right-click the OneDrive icon in the Notification area, and select View online.

  • Create a new sync connection on the computer running the older version of Windows. Read how to sync files with the new OneDrive sync client in Windows.

  • Use a computer running the Fall 2017 Creators Update for Windows 10 (or newer) to open the content.
