  # Notes about APPDATA paths:
  # Local app data should be used when an app's data is too
  # big to move around. Or is specific to the machine running
  # the application.
  #
  # Roaming app data files could be pushed to a server (in a
  # domain environment) and downloaded onto a different work
  # station.
  #
  # LocalLow is used for data that must be sandboxed. Currently
  # it is only used by IE for addons and storing data from
  # untrusted sources (as far as I know).
