On a DVD, several types of files are present, namely the BUP files, IFO files, and the VOB file. While the VOB or Video Object File contains the actual movie, the IFO file is an Index file. Its extension is .IFO, and it has all the information about the movie stored in the VOB file. This index file contains information about the time, place, and every other data that may be present on these three files. This file gives information to the player about each scene. It also lets the DVD Player locate audio tracks, subtitles, etc. Therefore, the IFO file is pretty crucial. It can be opened through a compatible video program like Windows Media Player, VLC Media Player, etc.
A BUP file is a backup file on a DVD with a .BUP extension. This file contains all the backup data of the original contents of the IFO file.
If there is malware, or faulty DVD writing, or some physical damage to the DVD, this BUP file can be used to restore all the data.
These files can only open with the help of several software programs or a suitable BUP file player.
