For network attached files you need to share the folder.
What is a rotor?

And to share folders from Windows or MacOS you need to refer to these articles in the Knowledge Base:

Sorry router …

So you’ve got an external drive plugged into your router to use it as a NAS? Have you read this article in the KB?

Does the router require a username and password to be set up in Roon to access the storage?
