Thanks Bob. I'll give it a try.
For my understanding: why do you recommend read-only? As I want to use the "Rename, Move, and Copy Files" function - which requires write access I expect.
Alternatively, I'm even more fine if I can use the "Rename, Move, and Copy Files" function from the Windows laptop, but here I'm struggling with the Library: the function does not work when I load the Libary on the Id server.
So I have now created a new local Library on my Windows laptop, hoping I can now edit file names/directories. But obviously it is not easy to maintain two different Libraries and keep them in sync... (I know MC offers a Library Sync option, but if I understand correctly, this copies files to the Windows laptop, which clearly is not what I want to do.
