I posted this on another message board and they told me to come here so hopefully someone can help me out. I just got the NWZ-A818 for my bday. The 8 GB version. I am able to put on a little over 2 GB's worth of music before it says memory in device is full. So I click properties to see the memory on it and its full. So I delete everything I put on there and when I clicked properties again it said I was using over 5 GB's of memory. Even though I went through every folder and they were empty. If someone could help me out it would be greatly appreciated.
