I want to know if it is possible to exclude certain files (either those that match a particular pattern in the filename, or those that have a particular extension) when scanning a hard disk for movies. The reason I ask for this is that I use XBMC as my media player, and I have all of my movies in separate folders (around 2,400 movies), and in each folder i also have the trailer for the movie, named <movie name>-trailer.mp4. Given this, I would like to exclude the trailers when scanning my hard drive for movies, or a way for XMM to know that the mp4 file is the trailer for each movie found. Please let me know if this is possible. Thanks.
