What is a BU file?
Video file created with a Samsung DVR, such as a CCTV (closed circuit television) recording system; contains surveillance video in a proprietary Samsung format that can only be played back on Samsung devices or with Samsung's video software.
BU files are saved along with a corresponding .DB2 file that contains information about the BU file. BU files are often several megabytes in size while DB2 files are typically only a few kilobytes.
