PSR-SX900 File Operations

[Joe W]

I've started working on updating the Lessons > Playing section.  For File Operations, I decided to put all the SX material in one lesson and then leave the earlier series of file operations as is for Tyros and PSR owners.

Here's a link to the SX file operations lesson:

Since SX screens can be difficult to see on the keyboard, I have included many screen shots all with links to a larger version of the screen.
