WTV020-SD-16P, Skipping, and Previous, or Acessing specific files.

Is there a way to access a specific file on the MicroSd card, so I can have it play a the third file, if a specific button is pressed or somthing?

Is there a way to control the module via arduino in general. Apart from the library somone else so graciously created, how can I skip or access the previous file via an arduino initiated command?
