How so? I don't follow. It's still the same optimized, global, secure key-value store. It just has a different interface if you cannot possibly fathom using different tools than the ones you use to deal with the filesystem.

Pwsh is pretty neat in that regard. Besides the actual filesystems drives, many systems have "providers" that allow you to treat their objects as files: the registry, environment variables, the functions defined in your session, the variables, the aliases... Unix's "everything is a file" became "everything is an item".
