// Drive. Creates a file iterator named 'previousIterator'.
const previousIterator = DriveApp.getFilesByName('Untitled document');

// Gets continuation token from the previous file iterator.
const continuationToken = previousIterator.getContinuationToken();

// Creates a new iterator using the continuation token from the previous file
// iterator.
const newIterator = DriveApp.continueFileIterator(continuationToken);

// Resumes the file iteration using a continuation token from 'firstIterator'
// and logs the file name.
if (newIterator.hasNext()) {
  const file = newIterator.next();
  console.log(file.getName());
}
