Disklavier

I have a Mark IV.  I would like to transfer solo piano MIDI files direct from a notebook computer to my Disklavier to play.   Chapter 7 [p. 92] of the Advanced Operating Manual "Setting Up The Disklavier for MIDI Data Reception (MIDI IN) advises to install the USB driver to the connected device [in this case, the connected computer is a Lenovo notebook running Windows 10 - 64 bit].
The YAMAHA Disklavier USB driver download to my device was completed and I have connected the USB cable from the USB port from the notebook to the Disklavier I/O center.
I have downloaded several solo piano only MIDI files to my computer that I want have play on the Disklavier.  I now need help in completing the steps necessary to make the piano play direct from the notebook.    The manual goes into detail about selecting channels and I know nothing about that.  I would like some guidance from here before I begin arbitrarily punching buttons and tapping the prc-100 screen.  Any possibilities that some of you may lend some guidance to this tech-novice?   Need to know 1) if I have the proper cable?  2) what initiates the transfer of data? 3) what steps do I take in order to have the files transfered?   
I would like to learn how to construct playlists and be able to have the ability to have numerous files for continuous, uninterrupted playing.  
thanks to all,
