[Resolved] Can I Play BUP Files on Windows?

Alright, let's start with the basics. A BUP file, short for "Backup", is a type of file commonly found on DVDs. These files work hand in hand with IFO (Information) files to help your DVD player or computer navigate through the video content. Think of them as the behind-the-scenes crew of your favorite movie – they're not the star of the show, but without them, the whole production falls apart.

You'll typically find BUP files hanging out in the VIDEO_TS folder of a DVD. They're like the understudy for the IFO files, ready to step in if the main file gets corrupted or damaged. It's a clever little backup system that keeps your DVD viewing experience smooth and uninterrupted.

Now, here's where things get a bit tricky. Unlike your run-of-the-mill video files, you can't just double-click a BUP file and expect magic to happen. Windows doesn't have a built-in BUP file player, which is why you might be scratching your head trying to figure out how to open these mysterious files.

The thing is, BUP files aren't meant to be played directly. They're more like the supporting actors in the grand play that is your DVD. To actually watch the content, you need to access the entire VIDEO_TS folder structure, not just the individual BUP files. It's like trying to watch a movie by only looking at the script – you're missing out on all the action!

There are three types of files in a VIDEO_TS folder:

VOB: Contain all actual video and audio data.

IFO: Information files store the navigation and configuration information of a DVD video.

BUP: Backup files of IFO files and they can be accessible when the IFO files are damaged.

Apparently, directly opening BUP files isn’t an appropriate way. If you have found some .bup file players from the Internet, it’s quite possible that they are inflated or actually help you play DVD videos in an indirect way. So how to correctly play BUP files? Here are the solutions!

The right way is putting all the IFO, BUP and VOB files into a Video_TS folder and play IFO files connected with actual data files.

You can directly play VIDEO_TS folder using Windows Media Player with MPEG-2 decoder installed on Windows 7 and old versions. It should be noted that Windows 10/11 has removed the DVD playback capacity but it provides a new DVD Player, which costs $14.99.

Instead, your best bet for playing BUP files (or rather, the content they're associated with) is to use specialized DVD player software. Programs like VLC Media Player, PowerDVD, or PotPlayer are excellent choices. These applications are designed to read the entire DVD structure, including those elusive BUP files. To use these players:

- Open the media player.

- Look for an option like "Open Disc" or "Open Folder".

- Navigate to the VIDEO_TS folder containing your BUP files.

- Select the folder or IFO file and hit play.

- Alternatively, right-click on the VIDEO_TS folder and select "Play with YOUR PLAYER".

Voila! You should now be able to watch your DVD content as if you were using a physical DVD player.
