  Filenames starting with ':' are bookmark menu entries.
  The parent entry (subtree != NULL) must also have ':'.
  The second and third characters should be 0.
  The fourth character gives the bookmark index, starting from 0.

  Filenames starting with '!' are backlight timer entries.

  Otherwise the timeout in seconds is the value/100.
