.PRO4 File Extension

Multimedia presentation created with ProPresenter, an application used for creating productions for church worship services; may contain multiple presentation slides as well as references to audio and video files; also stores the timeline for when to show each slide; used for saving the documents in the application's Library pane.

PRO4 files are compatible between Mac and Windows versions of ProPresenter.

NOTE: PRO4 files do not include any referenced multimedia files (e.g., .MP3, .MOV, or .WMV files). If you wish to include multimedia files with the playlist, use a .PRO4X file instead by choosing File → Export as Pro4 Bundle....
