Clicking the Playlist content tab in the playlist detail opens the page where we manage the media files of the playlist and add new ones.
The playlist content
The table listing shows the media files included in the playlist and their properties: the media type, name, length, author and editor, the state of the encoding and of the editing of the descriptive data, the protection setting and the date of creation or of the last edit. With the Remove button at the end of the row we take the file out of the playlist.
The playback order
The listing is sorted by the order of the files in the playlist, in the way they will be played. We change the order by dragging the target icon
in the first column with the mouse; the dragged row is placed before the row over which we drop it.
The state of the media files
Only items in the 
“ready for playback” state will actually be available in the playlist. We therefore pay attention to the indication in the Status column, or in the Encoding and Editing columns. We get quickly to editing the media file in question by clicking its name directly in the table.
The security of the playlist items
Whether each media file can be played is evaluated separately, and the security of the playlist itself does not affect it in any way.
Adding media to the playlist
We add one or more media files to the playlist in the dialog opened with the Add media files button, which makes it possible to search for files by name, to filter them and to add several selected files at once.
The checkboxes in the dialog listing select individual files, the pair of icons in the header selects or deselects the whole page of results, and the Use selected button adds them to the playlist.
