I've updated my Movie Cleaner. Primarily designed to be used with xbmc, it will create the necessary movie .nfo files and thumbnails for movies. Movies must be stored in individual folders & it is the name of the folder that is used as the movie title.
There are some other movie cleaners out there which do more than mine i have to admit. But it does a simple job well and satisfys my needs. Let me know if you enjoy using it.
