Where does eClicker store system files including playlists and/or questions on my mac? I'd like to know for two reasons: first, I would like to ensure these files are being backed up in case current files get corrupted or damaged. Second, I would like to clean out vestigial eClicker files from older versions (e.g. bignerdranch files) that are stored in various places, and need to know which are essential and which are deprecated. I currently rely on exporting playlists and questions, but there may be issues, such as impaired backwards compatibility of playlist files after software revisions occur.
