I do not know if I understand your question correctly. So please ask again if this is insufficient.

Do you want dragn drop kind of feature? It works similar for .save file using do in linux. You can select and copy in the file manager and just click append button in the do window. M ac will have similar feature soon.

Other than that, I recommend using RD to define your working directory.

You will see your project file right away when you do jo.

Best,
