Failed to write file, no error message

[Trumpet63]

I run the program from command line on a songs folder with a single song. The program prints to console some basic information and says it is successful. It creates a new directory which I assume is meant to contain the .sm file, but the folder is empty. I wanted to try adding a print statement to the try-catch where there might be an error message but I don't know javac very well and had to give up on that idea.
