Open Finale files in Dorico directly, without XML export?

How can you do this, please help in this

Welcome to the forum.

First of all you have put your question into a Developer forum, not Dorico. I hope it is ok if I move your post to the Dorico Forum.

Opening Finale files directly in Dorico is not possible, because Finale uses its own proprietary format and this is not known to Dorico. So your way to move files over is via MusicXML.

There’s also already another thread about this topic with some further discussion:
