I am stumped over this seemingly very simple task; and I couldn't find anything in the manual. I have a sansa zip and use the back button to move to the parent directory in browsing mode. In playing mode I use long-menu button to move to browsing mode. From there I can't find any way to move directly to the parent directory. The back button brings me back to the now-playing screen. Is there no way to move back up the directory structure while playing without having to move back to the main menu and down again from the root in the files menu?
