A PRO6PLX file contains a playlist bundle created by ProPresenter 6, which is a professional presentation program. It stores a playlist that may include one or more .PRO6 files, video files, image files, and audio files. PRO6PLX files enable playlists to be archived or transferred between computers.

A playlist in ProPresenter allows users to organize individual presentations, songs, videos, and other content to assemble a multimedia production. When a user exports a playlist, ProPresenter creates a PRO6PLX file to store the playlist. You will most likely only encounter PRO6PLX files if you use ProPresenter to display complex presentations and export a playlist. You may also receive a PRO6PLX file from another ProPresenter user looking to share his playlist. To export a playlist as PRO6PLX file, click the playlist, then select File → Export Playlist.... To open a PRO6PLX file, select File → Import → Import File.... NOTE: ProPresenter is used to assemble various types of visual productions for sporting events, concerts, church worship services, and conferences.
