What are IFO, BUP, and VOB files and how do I play them?

Question

I downloaded what was supposed to be a bunch of videos onto my computer, but hey ended up being IFO, BUP, and VOB files. How do I play them? When I click on them and have my computer search for information on them, it doesn't come up with anything. What do I need to do?

Answer 1

IFO - An info file associated with a .VRO video file. The .VRO file contains the video stream and the .IFO file contains various scene and timing information. This is different from a .VOB file where that information is included in the file. Several manufacturers use .VRO/.IFO files. If present, the file VIDEO_TS.IFO consists of control and playback information for the entire DVD. VIDEO_TS.IFO is known as VMGI (The Video Manager Information file). This file is required to be present on a DVD-compliant disc.



BUP - BUP files are just backup files of the IFO files. If the DVD player cannot read information from the VIDEO_TS.IFO, it will attempt to get the required information from this backup file. This file is required to be present on a DVD-compliant disc.



VOB - A VOB (Video OBject) contains several streams multiplexed together: Video, Audio and Subtitles. Video is MPEG-2, audio can be AC-3, Linear PCM, Mpeg 2 multichannel or MPEG1 layer2 2 channel audio.

Answer 2

These files are the contents of a DVD. If you have a DVD burning program and drive, you could burn them the way they are onto a DVD and possibly play the movie on a standalone DVD player.



To play them on a PC, you'll need to have a DVD player software like PowerDVD. In such a program, it is possible to select a folder on your PC as a video source. There you have to select the folder where your IFO, BUP and VOB files are.

Answer 3

I believe these are DVD format files. Use a software like real player or even windows media player that has a DVD decoded in it. That should work....good luck
