What is

The most common use of the BUP file extension is as a backup file for the DVD IFO. Many programs like the InterVideo Win DVD, Apple DVD Studio Pro, and Nero ShowTime use this format as a backup file for their IFOs.

The IFO files are used in storing different information on a DVD such as the tracks and subtitles. The BUP file is helpful in case the IFO file is corrupted or unavailable for use. The media player will instead use the BUP file whenever the IFO is not available.

On the other hand, the BUP file also works as a file for the CD Indexer. This application is an old program for Drive Mirror 2.
This can be used to create drives or CD mirrors. CD Indexer copies the entire file including its system, other hidden files, and the catalog structure.
Basically, this application works similar to a disk catalog, wherein the user can look for information through a search engine.
Any file created with the CD Indexer has the BUP file extension. Another old program using the BUP file is the Softcode Tracker.
For this, the file works as a backup for the contact manager. Also, the BUP file can work as an update file, specifically for the PC-Bibliothek application. For this, the file assists in the regular updating of the application. Brother Embroider
