My bad. I have to confess that I abandoned that one because I couldn’t figure out how to a) progress from a one-shot synchronisation to a permanent synchronisation service, b) be sure of its robust treatment of all files, and c) integrate it as a background task that needs almost no attention from me, i.e. just like the Synology Drive Client. So much for my initial enthusiasm for your suggestions…:shame:. Thank you for your patience with me!
My question with this thread is perhaps a total pipe-dream. Is it possible that “Synology Drive Client-xxx.exe” might work somehow under Leap 15.3./Gnome desktop just as the equivalent “Synology Drive Client-xxx.rpm” used to? What is required to achieve that?
