Roadmap supports the system "Open In" feature to import roadmap files (with the .rdmap extension) shared through email, AirDrop, and other apps.

For example, to import a roadmap file from Google Drive: open the Google Drive app, navigate to the document, and then copy it to Roadmap through the "Open In" menu.

The imported document is added to the "My Documents" group. (If another document is currently open, the new document will be imported after you return to the Home View by closing the current document.)
