Changing title and file path?

I want to change a title, say, from ABC to XYZ. Changing it on the title page of the piece is no problem. However, I want to change the title in the scores folder (the mscz).
The file path in Score Properties reads Musescore3/Scores/ABC. How can I change it to XYZ in the score mscz folder and the file path? Or is there an easier way?
