OpenMTP is a desktop application that enables file transfers between macOS computers and Android devices over USB using the MTP protocol. It functions as a dedicated file manager client for Android devices, providing a split-pane interface for browsing and managing files on connected device storage, including internal memory and SD cards.
The application supports transferring files larger than 4GB in a single operation without splitting or errors, and enables moving files between local and device storage panes through drag-and-drop interactions. It includes a grid-list view renderer that switches between icon grid and detailed list layouts, and provides an opt-out toggle for anonymous analytics collection in its settings.
