BUP file and creation

Whats a BUP file, is it needed and how do I create one? I burnt a DVD with a missing file (it was corrupted on the original) and now it won’t play! Any ideas :confused:

It’s a BackUP file - specifically of the IFO files.
Most editors create them automatically, but there’s nothing to stop you making a a copy of the corresponding IFO file using Windows Explorer, and then renaming it.


So why do you need a backup of the same IFO file? Also, if its not present on the DVD, would that syop it plying? Thanks!

  1. The DVD specification says so. (Why do you need a backup of anything? In case the original can’t be read!)

  2. Probably. Most likely depends on how fussy the player is.
