these instructions are for SD card reader. You can copy entire floppies in the SD Tools menu of the 7k, under Copy From Disk. Using the card reader will save an enormous amount of initial copy time and effort if you have a large archive of technics files on your computer.

To copy to the correct folder on the SD card in the card reader you just open both source and destination windows and highlight the files to copy in the source window, then drag them with left mouse button held down to the destination folder, then release the mouse.

Alternatively highlight the files to copy and use Edit/Copy menu in the source window and Edit/Paste in the destination window.
