text: This little guy works right out of the box. No formatting required. There is a music folder already on the device so, just drag and drop your music in that folder or you can re-create the folder and name it something else. Once the music is on there, using the interface you can choose different ways to access that music (shuffle, accessing the folders directly or playing all the songs). The device itself is very light, think and can easily fit in your pocket. Not much to it really. It comes with a cable that allows you to connect to the computer to be able to put music, video or books on the device. It is also used to charge the device. It comes with headphones as well, which are pretty cheap but get the job done. My only gripe with the device is that even though it is light, it does feel like I can break this thing if I sneeze. Doesn't feel durable. But, all in all, great device for the prices.
