Most of the iRiver devices have USB Mass Storage support. This means that when you connect the device to the PC using the provided cable and enable USB support, the storage of the device will appear as a removable drive in the folder ''My Computer''. From there you can browse and copy music from your device and then you can add it onto any iTunes playlist. On the other side you can use an official application that makes it even easier. iRiver Music Manager provides a more simplistic way of transferring files to and from your iRiver device.
