Passing a string to open file on SD card

In reply to PaulS, there are hundrends of sounds effects and it is much easier for he end user to keep track of these and what they are for used for and more importantly, when. The reason for the 8.3 filenames is that this is what the MP3 Music Maker Shield requires and will not understand any other format.

So, if one of the sound effects is a farting noise, the user must name the file FART____.mp3? Why?
