Audio File Setup

The DF Mini Player will play back both mp3 and wav files. However, the program play back tracks based on index. The index is determined by the order the files are loaded onto the card. It also expects all files to be loaded into a sub directory on the card called "/mp3".

When using a MAC to load files, it will create hidden files that will cause the playback to seem like it's not working. You'll need to use the terminal window to rm all of these files and directories from the card.
