I think the "hide the file browser" has had some pretty mixed results when attempted on mobile. File browsers and file extensions come in handy. For example, the zip/archive workflow. Does it make sense for all archives to live under the zip app? Does it make sense to have to share files to and from a zip app in different bespoke app level UI? If its OS UI how is it really any different than a file browser?
