I ripped a batch of CD's to my laptop's new FLAC Music folder and then sent that first batch to the new SanDisk Ultra 512GB micro SD card using the card reader on my Dell XPS 17. Have listened to first batch in my Cayin N8 Brass Black DAP, the uncompressed FLAC music sounds fantastic and all the album artwork is available (as opposed to only 70% in my WMP WAV). How do I add the rest of the CD's when I've finished ripping them? Other than individually sending them to the micro SD card, one by one? Or I delete the first batch from the card and send the complete FLAC ripped collection to the card in one go? Am I missing a cunning plan here?
