Depends on the version of Java -- if you are using Java 5 or later and
you just want to copy a file then the java.nio package will
give you much better performance. Do something like:

FileChannel in = null, out = null;
try {
in = new FileInputStream(args[0]).getChannel();
out = new FileOutputStream(args[1]).getChannel();
out.transferFrom(in, 0, in.size());
} catch (IOException e) {
e.printStackTrace();
}
finally{
//…close the channels
}
