I purchased a Fiio X3 from Advanced MP3 in England and the sound quality is fantastic, with files stored in the internal memory.
However I cannot get the X3 to recognise my Sandisk 64GB Mobile Ultra TransFlash Class 10 Micro SD cards. I have used the default format of ExFAT and also reformatted using SDFormatter as FAT32 via both Quick Format, Full (erase) and Full (overwrite).
I can copy files via my PC and USB to the SD disk in the X3 and the PC sees the files but when I 'Browse Files' - 'Micros SD Card' I get the message 'Playback Failed File Not Found'
This is really frustrating, I just want to store and listen to music.
Please help me because at the moment I just have an X3 with 8MB internal memory usable which is not what should be the case.
Firmware is FW1.23EN
Thanks in anticipation
