Dropbox Paper lets you put documents into folders. A doc cannot belong to more than one folder, but it can be part of no folders. The Dropbox Paper interface indicates a document belongs to no folder by marking it with the word "unfiled".
If I want to see all the Dropbox Paper documents in a folder, I can navigate my way to that folder. But there doesn't seem to be an equivalent for unfiled Dropbox Paper documents.
How do I list all the Dropbox Paper documents in my account that are unfiled?
