What Is BUP File

BUP files are backup files created by various computer applications and stored on the PC. These files are usually created from DVD files as image backup files to create a backup image of the contents on the DVD to the computer.

If you are playing a DVD on your computer and you cannot read the .IFO file due to scratches on the surface, you can use the .bup file to retrieve the data. Programs that archive and store user information also use BUP files. In some cases, the .bup file will contain a backup file created by the application before the application crashes to prevent data loss.

Tip: To learn more information about backing up files, you can go to the MiniTool official website.

BUP, VOB, IFO, TS, and VOB are all related to DVDs. The following are the details.


VOB (Video Object) is a native storage file format. It is a container format in DVD-Video media. This file format contains a majority of the data that is stored on a disk that includes digital video, audio, navigation content, DVD menus, and subtitles.

A VOB file is the core of any DVD video and is often found in the VIDEO_TS folder with the .vob extension. This is a movie data file. It is the source of the actual movie data such as MP2, DTS, AC3, as well as a MPEG-2 video stream. Files in the VOB format might be encrypted.


Usually called ISO, an ISO image file is an archive file that contains all the data on CD-DVD, Blu-ray, or CD (including file system). ISO files can be used to create backups and distribute large programs that need to be burned on discs. The file extension is .iso, and the name is taken from the file system used by optical media, which is usually ISO 9660.


TS stands for Transport Stream, which is a video stream file that stores the video on a DVD. The file can also store audio and data information. The file uses MPEG-2 compression to compress video data. These files are saved on DVDs with multiple numbers and can be played by different players and editing tools.
