How do I export settings from Nexus fonts?

I am switching from one PC to another, and can’t figure out if I can export my already setup collections so that I don’t have to be redoing all the font sorting.

It depends on the operating system that you’re using. You just have to copy the font files related to your collections, upload it to the new PC locations.
else, you can use third party applications that can help you in managing fonts and collections.
