What about using FileChannel (requires JDK 1.4)?

//Create channel on the source
FileChannel srcChannel = new FileInputStream(inputFile).getChannel();

//Create channel on the destination
FileChannel dstChannel = new FileOutputStream(outputFile).getChannel();

//Copy file contents from source to destination
dstChannel.transferFrom(srcChannel, 0, srcChannel.size());

//Close the channels
srcChannel.close();
dstChannel.close();

HTH,

Frank

This is a trick question, right?

If someone comes up with a technique for copying files that doesn't
require any reading or writing, we'd all like to hear about it :)
