What is an MPLS file? An MPLS file is a Blu-ray playlist that defines the playback order of video clips on a Blu-ray disc, including the order of chapters and branching video paths (like language or viewing options). It does not contain actual video or audio data, but instead lists the sequence of media files, known as "M2TS streams," that make up a full movie or feature. MPLS files are typically named with a five-digit code (e.g., 00001.mpls ) and is saved in the BDMV/PLAYLIST folder on the disc.

More Information Software Blu-ray players such as Leawo Blu-ray Player or PowerDVD, and Blu-ray authoring tools, can interpret MPLS files to manage and preview disc content. While players typically handle MPLS files in the background, users working with Blu-ray rips or backups may encounter MPLS files when organizing or analyzing disc structure. Specific information that an MPLS file typically contains: Clip references: Which M2TS files (clips) are played Start and end times: Defines time ranges within each clip Playback order: Which clips to play and in what sequence Chapter information: Points that correspond to user-accessible chapters Multi-angle and multi-version logic: MPLS can reference different angles or language versions without duplicating video data
