Is there an easy way to backup all my favorite styles, (other than taking a screenshot) and also to backup any hybrid styles I create?

I lost all of this at one point when I restarted with a new computer. I am running BIAB 11.5 from my hard-drive, but I have everything backed up to the BIAB external drive, all my songs etc, I try to keep the program updated in both places so I have everything protected and ready to run... but... how do I save those styles to the external drive as well?

Tried looking in the help. And searching this forum. Excuse the Newbie Q, and thanks for any help.
