Hello!
For some reason, I can’t open a .glyphspackage file (my Glyphs 3 is up to date).
It’s my first time with a .glyphspackage file (it was exported via Fontlab), when I click on it, it just says: “the file “…” can’t be openned”, don’t know if the file is corrupted or if I can try something, any idea?
Thank’s! 
Can you please send me the .glyphs file to support (at) (this website without ‘www’ or ‘forum’). I will have a look.
Thanks for the file. There are some invalid custom parameters in the master settings. I fixed it in Glyphs so that it can handle it.
hello, I’m having the same problem. I’m not sure why I can’t open the file on my glyphs mini app
Glyphs Mini cannot read .glyphspackage files.
Chances are that when a file is stored in the .glyphspackage file format flavor, it contains data that goes beyond the features of Glyphs Mini. However, if you would like, you can send me the file, and I will have a look to see if the file is compatible with Glyphs Mini. Post the file here or send me a private message here on the forum.
Or, you can do the conversion yourself using one of the following tools:
