44 *
45 * This source displays files that rhythmbox cannot find at the expected
46 * locations. On startup, it does a file access check for every file
47 * in the library, hiding those that fail. This source sets up a
48 * query model that matches only hidden entries. It displays the file
49 * location and the last time the file was successfully accessed.
50 *
51 * The source only displayed in the source list when there are hidden
52 * entries to show.
