Hello
I am sorry that I am unable to understand what you mean here. Do you mean that MarginNote will automatically move the document into its folder? I wasn't able to replicate this with my Mac or iPhone. Can you please give me a more detailed description of what you mean? It would be better if you could explain it with a screenshot or a screen recording.
If you want to access files that you don't want to move to MarginNote, you can use the method described in this link. Sorry that it is a little complicated.
Kind Regards,
MarginNote-Sushi
