I too have encountered this issue. It is a common problem with the MS socket (such that they don't provide a parameter for file types). The way I worked around this is to be sure you are in Binary mode e.g. this.BinaryMode = true; before calling the SendCommand or reader/writer functions. Same for downloading. Beyond that, I had no other problem.
