Thanks for what appears to be a very useful task you've done. I'm not sure I understand it, though. If I install your utility will mplayer, for example, necessarily be selected as my player of, say, mp3 files? What if i wanted them to be played in Canola or in another app? Can I use it to associate other files with programs or are all the associations pre-determined within the utility? I can't remember what, but I know I've wanted to change some associations for file types -- will this utility enable that? Thanks!
