New to JRiver and a bit naive. OK a LOT! have used the keyboard for a couple weeks and today got internet to my music computer. So I downloaded the app to my iPad. Works ok but I cannot look up file types. I like to play say all my FLAC music or maybe all WAV files. For the life of me I cannot discover how to use the remote app to lookup file types. Can it be done? of am I SOL?
