The CD was included in my package with the 2 floppies and the SD card packed in the same plastic bag. The CD is white and blue labeled Applications & Drivers for SX-KN7000
The Song Manager application does allow you to transfer songs back and forth over a USB cable between the PC and the SD device once it is all installed. Speedy data transfer is not an attribute of this program but other than that it does work.
The Audio Recorder allows you to record or playback in WAV, MP3 etc.
The SD devices are made by Panasonic check out
