Don't do that. It will reopen and close the file on every 
received chunk. Not only is it slow, but if the file is 
renamed/moved/deleted while the download is occurring, the file 
will be corrupted. The same will happen if you run the program 
twice, if you don't clean up.

The correct way is to open a File once, then use rawWrite for 
every received chunk.
