On Windows 10, OneDrive users can now sync their Desktop, Pictures, and Documents folders and their content to the cloud service to make sure those files are protected against hardware failure and malware.
Although the new feature is useful and straightforward to configure, users can run into a number of errors and problems because there are a few limitations and known issues.
How to fix problems using folder protection in OneDrive
The following list includes errors that you may encounter during the set up and what you can do to fix them:
Folder protection is unavailable
Usually, you’ll get the “Folder protection is unavailable” error because your computer may be part of a domain, in which case you cannot protect the files using OneDrive.
To resolve this issue, contact your network administrator to use another solution to backup your files in known folders.
Folder is on a different volume
You’re likely to run into the “folder is on a different volume” error, for example, if OneDrive is configured on the D: drive, and your Documents folder is located in the C: drive.
It’s not possible to protect known folders using this scenario. The only way to resolve this issue is to reconfigure OneDrive in the same drive where the known folders you’re trying to protected are located.
Right-click the cloud icon in the taskbar, click Settings, and click the Unlink this PC option. After unlinking, sign in again and choose the root folder location to be on the same volume as the folder you want to sync.
Important folders aren’t in the default locations
This error indicates that the folder with the error includes another known folder (Documents, Desktop, Pictures, Screenshots, Camera Roll, OneDrive), and they can’t be protected until the contained folder is removed to its original location.
Folder contains a reparse point
If you get a message of a folder containing a reparse point, it means that the folder you want to protect contains a special file type that links parts of the file system together.
In this case the items can’t be protected. You can quickly resolve this issue by removing the file causing the issue.
Folder isn’t selected for syncing
If the selected folder isn’t syncing, right-click the cloud icon in the taskbar, and click Settings. Click the Choose Folders option, and then make sure the folder you want to protect is selected.
If Pictures folder is the one with the error, make sure that Pictures, Screenshots, and Camera Roll are all selected (or don’t exist). Also, it’s possible that the OneDrive folder has a different name from the Windows important folder.
File type can’t be protected
OneNote files (.one, .onepkg, .onetoc, .onetoc2) as well as Outlook database files (.pst) that aren’t already in OneDrive won’t sync automatically.
To resolve this problem, move a OneNote notebook to OneDrive, or remove these files from the folder you’re trying to upload to the service.
File exceeds the maximum file size
OneDrive only accepts files up to 20GB, anything over this size won’t sync. Unfortunately, you’ll need to remove these files on the folders that you want to protect to stop getting the error.
File exceeds the maximum path length
If you get the message of a file exceeding the path length, make sure the path and file name together are less than 520 characters on Windows 10.
In the case the length is more than the supported, then try to shorten the file name and move the folder containing the file closer to the root folder.
File name isn’t allowed
File you upload to OneDrive cannot start with a space or including certain special characters, such as \ : / * ? < > ” |. To avoid problems, rename the files in question.
