File Extension IFO
DVD-video discs have two folders VIDEO TS and AUDIO TS. The VIDEO_TS has many files, which have extensions VOB, BUP and IFO. File extension IFO is an information file and have no audio or video data. IFO files contain information on DVD chapter subtitles, headings and audio settings. They also define the screens to appear on start-up. IFO files keep information on files such as VOB, which include PCM/DTS/Dolby Digital audio files, MPEG-2 Video.

File extension IFO is not particularly played but if a person manages to open the IFO file using particular software then the file would play VOB files or the DVD. VOD also known as Video Object for DVD is among the core files located on DVD-Video and has the movie data. To view VOB files one should have software that plays DVD and offers VOB playback support. As a security attachment, in case there is any form of corruption the IFO files have backup files known as BUP.
