Hi Doug,
First, please read the chapters "File Selection Display Configuration" and "File Management" in the S970 Owner's Manual (from page 26).
To see Registration Bank files, you must first open the Registration Selection display (press the two Regist Bank -/+ buttons at the same time, or press the "J" button in the Main Display).
It is now important that "Menu 2" is on the bottom right. This is the only way you can see commands like COPY and PASTE. (If "Menu 1" is displayed, press the lower button "8" to switch to the other display.)
If you only want to copy a single file, you can select it now (this will load it) and THEN press COPY.
To copy multiple (or ALL) files, or to copy one or more complete folders, FIRST press COPY and THEN select the desired files or folders.
Now press OK to complete the COPY command.
Now go with TAB to the desired target drive (e.g. USB 1) and navigate there to the desired folder (or create a new folder there and then select it to open it).
Now press PASTE to paste the previously copied files/folders at the current position.
Complete.
Hope this helps!
Best regards,
Chris
