Are the 1132 files on the SD card or spread out over the phones internal memory and the card ?
Is the 64 Gb card formatted to that size ?
Is the phone supporting 64 Gb cards ?
What happens if you use a card reader in/connected to the PC ?
All mp3 and i got any protected ones converted ,
currently all tunes are on SD Card 32gb,
new Card 64gb was formatted and folder was copied from Card to pc and all tunes accounted for once on pc in folder but still not all tunes made it on to new 64gb.
