The IFO Video file format

Technical details of IFO files
The IFO files are those files which store DVD information. These files are referred to as DVD Info Files because they contain information such as scene and timing. Files with the IFO extension let the computer, DVD player, or other device know which screen to show at start-up, where each chapter of the movie starts, where the audio tracks are located and where subtitles can be found. In conjunction with those files that store the actual audio and video data (VOb and VRO) the IFO is responsible to run the DVD.
