title: I want to get all my mega.nz account folders names
body: <p>I'm pretty new on Python and mega.nz api and I want to get all of my mega folder NAMES.
  I done this:</p>
  <pre><code>files = m.get_files()
  print(files)
  </code></pre>
  <p>And my output is this:</p>
  <pre><code>'5Xxl1YpK': {'h': '5Xxl1YpK', 'p': '5apkxBRK', 'u': 'HeQAbozUSnY', 't': 1, 'a': {'n': 'MAIN'}, 'k': (236358726, 3714021502, 3609314937, 957702177), 'ts': 1649753591, 'shared_folder_key': (1341100632, 611479631, 4161937411, 5464436), 'key': (236358726, 3714021502, 3609314937, 957702177)}
  </code></pre>
