How do I use the four cubes appear on my desktop?

The cubes are application programs of Power2Go Express mode. They allow you to burn "Audio CD", "Data Disc", "Video/Photo Disc", and "Disc Copy". You can drag files or entire directions to the "Audio CD", "Data Disc","Video/Photo Disc" dice, click the Rec to begin burning. Also you can double-click on "Disc Copy" cube to start the disc copy function. When one cube (function) starts the burning process, the other cubes are grayed out (disabled).
