Up front: this is new to me. So far I have been sharing files using Google Drive, but coincidentally 'discovered' that I could use a USB cable.
I connected my Samsung tablet to the PC and it showed up in both Opus and Windows Explorer.
However, in Opus all folders were empty, in fact, the folders weren't displayed in the right panel.
Maybe there is no support (yet)? Or maybe I should change some setting?
noticed the location bar reads some complex SID-bla-bla instead of This PC->Device name
