Files in VOB format have a .vob filename extension and are typically stored in the VIDEO_TS directory at the root of a DVD. The VOB format is based on the MPEG program stream format, but with additional limitations and specifications in the private streams. VOB files may be accompanied with IFO and BUP files. These files respectively have .ifo and .bup filename extensions.
