If you have PageFour installed on your PC, you will see an “Import PageFour Notebook” button on the actions menu toolbar.
On clicking this button, you will be presented with a list of PageFour Notebooks on your PC. Selecting one will import all files and folders from that Notebook into your current Atomic project.
However, any password protected files in PageFour will NOT be imported, as there is no facility for password protected files in Atomic.
At this time the file and folder order is not maintained when you import.
