How do I transfer my user files on my yamaha keyboard to my computer?

on my yamaha ypt e303 there are five spaces in which contain my own recorded pieces of music. I connect my piano to my laptop via midi to usb, but nothing happens. Some people say I need to go to a website and download things, but it doesn't help. I just want to upload my music to the computer as a file
