Convert MPEG to BUP

An MPEG file is an audio / video container that is commonly used. A BUP file is simply a backup of an original with an additional extension in the name.

This is done to preserve a copy that can be recovered if the original file is damaged or lost. A backup of an MPEG BUP files can be easily restored to its original state by changing the filename.



  1. Go to the BUP files you want to convert into an MPEG format. For example, if the file is in “C: / Backup”, double click on “My Computer”, then the “C: /” drive and then the “Backup” folder.
  2. Right click on it. A new context menu will appear. Select “Rename”.
  3. Delete the “.BUP” part of the filename so that the last five characters are “.MPEG”. For example, a file called “example.mpeg.bup” should be named “example.mpeg”. Click on “Enter” to finish.
