The Sega CD and Sega Saturn video game consoles both played games stored on CD-ROMs. These games used video files saved using Sega's proprietary FILM video format. FILM files were saved with a variety of extensions, including .FILM_CPK, .cpk, .film, and .cak.

CAK files were used in Burning Rangers, Dark Seed II, Revolutionary Girl Utena, Lunar 2: Eternal Blue, and Phantasm, among other Sega Saturn games.

How to open a CAK file

Because CAK files are so uncommon, most popular media players cannot play them. However, you can play CAK files using VLC media player, and you can convert CAK files to a more usable video format using FFmpeg.
