I have added a second hard drive to my recent clean install of Zorin 16 Core, by adding the necessary information into /etc/fstab. Now I can create, read, update and delete data to the drive through it's mount point, which shows in the left pane in the Files process. But almost every other application I have - for example, Audacious - cannot 'see' this 2nd hard drive or its mount point.
How do I correct that ?
After thought: I understand flatpak apps are sandboxed: could that be the reason why flatpak apps cannot see this additional drive?
