Why do you want to see my MP3 player code, when its not related to the question I am asking.
I could have a new project with no code, and I want to read the file name using the SDFAT library, and there would be no code to post.
The only thing relating to opening a file is the part I posted above, which is directly out of the example from the SDFAT library, I have gotten no where further than that.
