My preferred file manager is Asus File Manager. I wish to play a complete album of music through my DAB radio via Bluetooth. I cannot determine how to do it with this file manager. My backup file manager is ES File Explorer, Here, I choose sdcard1>Sounds, not Music, so that content of a particular album can be selected. Then, More>Play. I select all the tracks of an album in the same way in Asus File Manager. The options are "Move to", "Copy to", "Share" and "Compress", none of which is appropriate - "Share" not finding my Device, certainly. Is there a procedure I miss?
