Android :: Hiding Media Files From Music Player

I'm torn between which group to post this too, but since it is for an application I am working on, I guess I'll stick it here. So here we go. I have an application which downloads data onto the sdcard to be used by the application. Some of these files are sound or music files and the music player in android seems to parse these directories and add these files to the list. I'd like to somehow block or hide these files from the music player. Is there is a way to do this? I was thinking it may be possible to name my folder with a period at the beginning, since linux hides such files. I'm just not sure if that is going to hide it from the music player or if there is another way to handle this.
