  // A .zip containing "HelloWorld123.txt" with no path information has been created.

  // Perhaps you want to include a path in the .zip such that when unzipping, a sub-directory
  // is automatically created and the file unzipped into it.  Use PathPrefix:

  // (We'll skip checking the success/failure return value.)
