Failed to fix VirtualBox RTPathQueryInfo on shared folder path

How to fix: Could not save virtual machine settings – RTPathQueryInfo failed in shared folder in VirtualBox and Windows 10.

As I mentioned at the beginning of this article, the error occurs when the Windows XP VirtualBox machine (VM) maps the shared network folder on the Windows 10 computer to the VM Settings >> Shared Folders.

Failed to save virtual machine settings

In this case, the error is due to the fact that the host operating system does not have the Samba (SMB) protocol that Windows XP needs to connect to the shared folder. To resolve the issue, go ahead and enable SMB 1.0 support on Windows 10/11 (Host OS) as shown below:

1. Go to control panel and open it Programs and features.


2. press Turn Windows features on or off.


3. Check the Support SMB 1.0/CIFS file sharing feature and click OK. *

*Note: That’s enough for that turn on the SMB 1.0/CIFS client only.

*Note: If you still have problems, go ahead and install the Samba (SMB) protocol on the machine along with the shared folder.
