int len;

I read  API for java.io.InputStream read(byte[]) method and java.io.FileOutputStream write(byte[], int off, int len).
The read(byte[]) method returns an integer that tells me how many bytes were actually read in. So, I think I should only write that many bytes out. Doesn't your code above only work if the incoming file's byte count is evenly divisible by 256?

the code above does only write the number of bytes read, where len is the number of bytes:

file.write(buf, 0, len);
