Once a commercial DVD is copied successfully to the hard drive using Any DVD Shrink, you can find these three file types - IFO, VOB and BUP, in the VIDEO_TS folder.
VOB
VOB stands for DVD Video Object. It is basically one of the core files found on DVD-Video discs and contains the actual movie data, including an MPEG-2 video stream and support audio (MP2, AC3, DTS etc.) In order to view stand-alone VOB files, you need to have a DVD player software that supports VOB playback.
IFO
In video editing, IFO normally refers to a file on DVD-Video disc and stands for InFOrmation. IFO files basically contain all the information a DVD player needs to know about a DVD so that the user can navigate and play everything properly.
BUP
BUP files are simply backup copies of IFO files on a DVD-Video disc in case of corruption.
