What is a PRO4PL file?
Multimedia playlist created by ProPresenter, a program used for creating church worship service presentations; saves an XML playlist of audio, video, and .PRO4 files but does not include the referenced files (use .PRO4PLX files to include the audio and video files in the bundle); used for transferring presentations outlines between computers.
You can export a playlist in ProPresenter by right-clicking the playlist in the Playlist pane and choosing "Export Playlist."
NOTE: PRO4PL files are compatible between Mac and Windows versions of ProPresenter.
