The MPE file format is a digital video container standard developed by the Moving Picture Experts Group (MPEG) for compressed multimedia data. It functions identically to standard MPEG-1 or MPEG-2 files and is primarily used for storing synchronized audio and video streams on storage media. While this legacy format has been largely superseded by more efficient modern standards like H.264, it remains universally supported by media players and presents minimal security risks to users.
