I am puzzled. I have 5 of the Sandisk Clip Sport (8GB). I use them with a 64 GB MicroSD card, no problem.
Now I face an unexplainable (for me at least) issue. I have two file directories with lectures. Both look absolutely identical to me when I check the file type (with mp3tag) - but one plays without problem and one does not play at all and gives the message “File Format not supported”
Files in both are: MPEG 1 Layer III, Tag ID3v2.3, 128 kBps, mp3 Format
I put both in the 8 GB Storage area, still the same. One directory plays and the other says “File Format not supported”.
Would appreciate any idea how to solve this issue. Thanks.
