I am using Virtual Box 5.1 on top of Windows 7 Host OS with Ubuntu 14.04 LTS Guest OS. I have already installed VBOXADDITIONS_5.1.14_112924 and restarted the Guest machine. The folder appears as mounted underneath the Devices in Files, and it appears as shared on the Host machine.
What permissions do I need to change on my Host/Guest OS to make this shared folder work?
