A VOB file, also known as a DVD Video Object, is a file that uses the VOB file extension. VOB is the standard abbreviation for Video Object, a format you will definitely find in DVD-Video media. VOB files carry a lot of movie-related content, such as subtitles and DVD menu. They must also have video and audio data. The majorities of the VOB files have encryption and can only be opened by programs that can go past it. In the DVD root, there is usually a Video_TS folder that stores the VOB files.
