I am working on a project and I am having a hard time opening an SD .wav file. The SD card is formatted correctly (Fat32) and it initializes with no problems. The problem comes when I try to open the file or even using the SD.exists command. These commands result in "no the file does not exist.". I have used example code such as the "CardInfo" code and it does show the .Wav files exist on the SD card. I have also tried using a .txt file (same error) and made sure the file name was short enough (s.wav). Any help would be greatly appreciated.
