How merge two glyphs files?

I created one .glyhs file before,now I create another .glyphs file,I want to merge two files into one .glyphs file,How can I do?

Copy, paste.

Or add it as a second master? Then go into the Masters tab, and choose add other font as master from the plus menu in the bottom left.

I have this same question. When I try the Masters tab, and choose “Add other font”, the only item listed is the file I am already editing. I’m not sure how to choose the other font if I don’t see it in the list. What am I missing?

The other font file has to already be open by Glyphs too.


Thanks! That was not intuitive to me, but it worked. I appreciate the quick reply.
