What is a C93 file?
A C93 file is a video used in Cyberia, a video game produced by Interplay Entertainment. It contains a movie that is played within the game. C93 files were used only in the DOS version of Cyberia.
Since its founding in 1983, Interplay Entertainment has released over 300 video games. Only one version of one of those games uses C93 files. Cyberia was released for Windows, Macintosh, Sony PlayStation, and a handful of other platforms, but only its DOS release includes C93 files. The "93" in C93 likely refers to 1993, the year Interplay created the file format.
In 1995, Interplay resurrected and upgraded the C93 format for use in Cyberia 2: Resurrection. This modified video format was named, appropriately, M95.
How do I open a C93 file?
Because C93 files are so uncommon, most popular media players cannot play them. However, you can play C93 files using VLC media player, and you can convert C93 files to a more usable video format using FFmpeg.
