I know the stacking feature from XBMC and it is really nice. It works like this: Say, you have a movie splitted into 2 files: movie-part1.avi and movie-part2.avi (both in the same folder). Now, in XBMC there's only one entry in the list: 'movie' (and the calculated total running time). When you hit play, the first file starts and after that, the movie countinues automatically with the 2nd file. In XBMC this even works directly with disc-images (!). So basicly it looks for similar file names (using some reg-ex magic i guess), groups them together and automatically plays the individual files in a consecutive order without further manual action. Ofcourse, the movie can be split in more then 2 parts. It works with nearly all common filename-conventions e.g. movie-a, movie-b movie_cd1, movie_cd2 movie(cd1), movie(cd2), movie(cd3) and some other variations of the above.
