A QTL file serves as a shortcut to a QuickTime movie. It is a simple text document that includes the location of the media file and playback settings for the media.

QuickTime (.MOV) files can be played with QuickTime Player, a free multimedia player developed by Apple. QuickTime Player will open automatically when a QTL link is clicked as long as the Web server has QuickTime configured as the MIME type for QTL files.
