Just connect your iPod (making sure it's enabled for use as an external drive; check the setting in iTunes if you?re not sure) and run the program. Click the iPod icon and choose the appropriate drive letter for your player. Next, click the folder and choose the desired destination for your music. Finally, enable any options you might want, like Include iPod Folder Structure and MP3 Files Only (the latter helpful if you don?t want to copy DRM-protected AAC files). Click the arrow to begin the copy process.
