Is there a way of just deleting a folder where the fanart is located (wherever that might be), to remove any fanart of movies and tv shows that I have removed from XBMC? And will it rescan with just the moviies and tv shows I have still on XBMC. Having lots of fanart that is no longer tied to any media is diving me nuts.

I could put together a small script to delete the fan art. You would have to put all the movies you want to keep the fanart for in another directory though.

MilhouseVH put together a script that does what you want, more or less.
