I have this posts WebP add-on and unzipped it and am ready to move it to the file types dir. But confess, I am just a PC user and do not know where, and could not find out where with an internet search, where in the world is the 'file types" Dir. Doing a search in explorer did not find it either. I joined this forum in the hopes of getting an answer to this question. Non tech people want to have access to webp space savings and features as well. Thank you for you understanding help to us rookies.
