Hi Richard.Taylor
Thank you for a very comprehensive explanation.
I understood iCloud exactly like that, however I had some other folders previously syncing to iCloud as a backup solution.
So this query is mostly about syncing folders to iCloud without moving them from where they reside on my MacBook SSD file-structure.
But as I understand from information retrieved on the web and your comprehensive explanation, this is not possible on iCloud anymore.
It sure would be nice if I could back up / sync selective folders/files to iCloud without moving them to iCloud Drive.
In the past I made use of the "alias" function (or option) and in doing so good created an edited files in the original location (on my Macbook Pro SSD) and they would appear exactly like that on the iCloud Drive.
This would be used for remote emergency access to the selected files and folders if needed, without having my full document library residing on iCloud Drive.
Keep up the good work and thank you for the kind and informative response.
Regards.
Chris
