I have an mp3 player that doesn't use any library-management software, and I'm trying to come up with a way to automatically synchronise my music on my computer and player. Briefcase seemed like a decent way to do it; it takes all the files in the Briefcase and syncs the newest files in each location over-top of the older files in each location. I think. Anyway, I can't make it work. I copied the Briefcase folder from my computer to my player, and then when I told it to "Update All", I got a message saying the files in each location (despite having been copied not five minutes prior) were orphans and not synchronisable. Does anyone here have any experience with Briefcase, or can anyone recommend some simple, free file-sync software that doesn't come with bonus popup ads?
