What is the SUM file extension?
The
BUP file extension is used for one of the three types of files on the DVD disc. It is used for files that back up the IFO information files on the disk. The DVD video disk could therefore exist in theoretically without BUP files, even if it would be less reliable.
Not all DVDs will have files with the SUP file. This is because DVD means a digital versatile disk and can be used for more purposes, including net data storage. Extension of the BUP file is part of the DVD Video specification, which is a format used for discs designed to play on a separate DVD player.
DVD video files will contain three types of files. The most important is VOB, short for video object. These are files that contain sound and video content. A video from a disk that has only VOB files can still be played on most DVD players and computers, but with limited functionality. It is a controversy details of the video content. These details include times when any chapters begin and begin.They also include the information needed to distinguish between different sound tracks, for example where there are language or comment options, and different subtitles. IFO also indicates which video file to serve as a menu menu.
The final type is bup, short for backup. This is simply an IFO file backup, which means that every DVD video disk has one IFO file and one BUP file. The BUP file exists only to make sure that the disk can still work if the IFO file is damaged in any way. This could happen if the disk surface is blurred or scratched.
Another important difference between file types is the problem of encryption. VOB files are encrypted to prevent copied or "torn film content". IFO and BUP files are not encrypted.
It is possible for the extension of the BUP file to appear in other software contexts. AnyThe applications create backup key data files and simply add the BUP file after the main file type. This will prevent any confusion that could cause access to the wrong file. Upon and when the backup is needed, the BUP file can be removed from the file name, which means that the backup file will simply take over from the original.
