A VOB file allows a DVD to store and access all of the data necessary to play a movie on a DVD player. VOB files allow a DVD player to locate the video file, audio files, and streaming data required to play a movie and provide the user with the same control he/she would have in a movie that is played on a computer.OB files are essential to DVDs and can be taken from a disk in order to place a copy of a movie on a userâs computer. In order to do this, the user should simply open a DVD in Windows Explorer rather than play it through a media player. The VOB file will be located in the âVideo_TSâ folder.
