What Is a Bup File

BUP files are backup files that a lot of applications create to prevent the loss of information in the event the original file becomes corrupted or unreadable.

In DVDs, the BUP files are commonly used to create a backup of the .ifo file of the DVD's media content, such as subtitles, tracks, and menus.

If any .ifo file becomes unreadable or the file has become corrupted, the app, or in this case, the media player, will access the .bup file to run the media content.

The .bup files are not protected by encryption, and anyone can access them. With the help of third-party video conversion programs, the BUP files can also be converted to other video formats.

The .bup file extension is created and used by different applications for creating backups of their files, and each BUP file is not the same. It is first essential to confirm the program's BUP file that you want to open, as all BUP files are not the same and don't serve the same purpose.

BUP files are backup copies that each application creates for its purposes. If you're watching a DVD on your computer and want to open the available .bup files of the movie, you can do so by using a third-party media player. If it is a gaming application's .bup files, you will have to find an application that can open the BUP file of that application.
