QUICK ANSWER
Is it possible to convert BUP to IFO?
Yes - BUP converts to IFO.

Copy the .bup file and rename the copy to the corresponding .ifo name (e.g. VIDEO_TS.BUP to VIDEO_TS.IFO). No converter software is needed - the two files are identical by specification and the renamed copy fully restores disc navigation.

Why convert BUP to IFO?

The 1996 DVD-Video specification requires each .ifo navigation file to have a .bup counterpart stored in a different physical disc area as scratch protection. Because the files are guaranteed byte-identical, a renamed copy of a .bup fully restores disc navigation, allowing players and ripping tools to read chapter and title structure again. This is the one genuinely useful direct operation involving a .bup file.

How to convert BUP to IFO

Windows File Explorer FREE

In the VIDEO_TS folder, copy the .bup file and rename the copy to the matching .ifo name - enable 'Show file extensions' in Folder Options first if extensions are hidden.

VLC OPEN-SOURCE

After renaming, open the VIDEO_TS folder in VLC (Media > Open Folder) to verify that disc navigation works correctly with the restored .ifo.

CyberLink PowerDVD APP

Open the restored VIDEO_TS folder in CyberLink PowerDVD to confirm full DVD navigation after renaming the .bup copy to .ifo.

Quality & what to watch

  • Copy the .bup - do not rename the original; keep it in place as a backup after creating the .ifo copy.
  • Match the pair exactly: VIDEO_TS.BUP backs up VIDEO_TS.IFO; each VTS_xx_0.BUP backs up the matching VTS_xx_0.IFO for one Video Title Set.
  • A .bup contains no video or audio - the movie content is in the .vob files; use HandBrake or MakeMKV on the full VIDEO_TS folder to encode to MP4 or MKV.

Frequently asked questions

Do I need special software to convert BUP to IFO?
No - any file manager works since the files are byte-identical; copy the .bup and rename the copy to .ifo.

In File Explorer, open Folder Options and uncheck 'Hide extensions for known file types', then rename the copy.
Will the renamed IFO work immediately in DVD software?
Yes - the contents are identical by specification, so players and tools like VLC will read the restored .ifo normally.
