A CPK file is a video used in a Sega CD-ROM video game. It contains a movie played within the game. CPK files are one of many types of files saved in the Sega FILM file format.

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