Hyper Browser, a two-pane Android file manager

Field notes

The app is organized around two simultaneous file trees: local storage, removable media, USB, or Google Drive can occupy either pane, with copy, move, deletion, and folder creation between them. Its built-in gallery offers three zoom stages for reviewing photos before a file operation. The page says local browsing needs no account and describes the app as free of ads, analytics, and telemetry. Drive access uses Google's broad drive scope because the advertised operations include listing, opening, creating, moving, and deleting files.
