Is there a way to have Proton Drive's context menu entries appear? They show up in Windows File Explorer but not in Directory Opus. They are "Always keep on this device" and "Free up space." (I have "Hide Windows items on file context menus" UNCHECKED.)
I've found where the items are coming from in the registry:
I'm also only able to see Proton Drive's context menu entries in Windows File Explorer. There are only 2 entries as OP mentioned. By default neither is checked off after you install the Proton Drive app so you have to open File Explorer to set it to retain file & folder copies on your hard drive.
Naturally I can't see the Status icons of the Proton Drive files/folders from Directory Opus either. They show in File Explorer as a green checkmark icon (kept on device), sync icon (sync in progress), and cloud icon (available in cloud w internet connected).
