Re: Polished FileSystem API proposal

And here's an example:

// Copy the 1th byte of file1.bin to file2.bin
navigator.getFilesystem().then(function(root) {
  return root.openWrite(["file1.bin", "file2.bin"]);
}).then(function(handles) {
  return handles[0].read(1);
}).then(function(buffer) {
  return handles[1].write(buffer);
});
