Not OP, but having files and folder structures accessible in the OS helps with a lot of tasks and interoperability.
If I want to add media files to Jellyfin, etc, I can’t just drop them into the video folder remotely because I have it mapped to a particular folder on the drive. If I want to make a copy of a large folder, I first have to mount the cloud as a “remote” drive, then do the operation from there.
It’s much easier to access files and folders outside of a database if they are needed for anything outside of the cloud service. I know that there may also be some security and efficiency factors that make a database favorable, but in terms of ease of use, it is just more effort to use a fileserver that operates through a database.
Why use a software that requires an involved workaround when there is software available that already does it?
Nothing against NextCloud, buy it’s not the only solution available, and people have different needs.
