??? Im not confusing those at all. You literally just repeated what i said.

See desktop portals, and desktop environments you dont need to use the kernel for the folder structure. And shared implantations for adding them in are fairly trivial.

sounds like a you problem. if you think longer on it maybe you’ll come up with the obvious layer to implement it at that isn’t the kernel.

Indeed they are! Just don’t need them in the filesystem itself

Userspace concept is my point dont need them in the file system itself

yes, because folders are not something thats really worthwhile in a filesystem. they’re a vestige of an earlier time.
