Maybe I’m misunderstanding this feature, but it sounds like it’s supposed to save features, kerns and other info next to the UFO file instead of inside of it. But it doesn’t do anything with my existing files. What am I misunderstanding?
‘Save FDK parts’ saves all files required by FDK while generating a binary font next to the ufo file, if this is enabled.
The folder has the name of your <familyName><styleName>.fdk and contains several files like:
* font.otf (the final thing)
