Is it possible to play a file that is not in the root folder of the SD card?
If I put an mp3 file (“test.mp3”) into the root of the card, then it will play fine using the PlayWithName example.
However, if I put it into a folder (“test/test.mp3”), it will not play. The serial monitor shows no output.
Is this possible, or must all the files be stored in the root?
