That's not the install folder for Kodi.
If you don't know where's it's located you can use the Kodi File Manager to access the folder, see https://kodi.wiki/view/File_manager
With File Manager you can use Special Protocol paths that are essentially shortcuts to different parts of Kodi, see https://kodi.wiki/view/Special_protocol
So adding special://skin as a source will open the folder for the currently active skin, add a destination source to copy off to where ever you want to edit, and then copy back. However next time Kodi is upgraded your change will be overwritten. To keep the changes it's best to create your own version of Estuary by copying off the entire skin.estuary folder (source special://xbmc/addons) editing the files you want and copy to userdata location (source special://home or special://home/addons)
