Artwork Downloader

When I run Artwork Downloader on my Fire TV, it downloads all the available images for a movie and they display correctly in MQ 7. However, when I go to the external drive where the movies are located, I see only the movie file with extrafanart and extrathumbs folders under the movie directory. The other images (banner, clearart, disc, logo, etc.) are not located in the movie’s directory. Any ideas where they are being stored by Artwork Downloader?
