Recently I went to China and bought a MP4 player with 2GB memory with an amazing price. When I start to copy the files to the MP4 Player, I experience some problem. At last I decided to format it. In the first 2 time, I can format it as 2GB. But then the device size change to 109M. How to compress the drive to 2GB with only 109M? Is there any way that I can change the size back to 2 GB or at least bigger than 109M.
