“Multiple .VOB file to one file? - Looking for an easy software program that will put all of my .VOB files from a DVD movie to one file without any quality loss. Will HandBrake merge multiple VOB files into one? Also do I have to add the .VOB files to the software in the order of the files from beginning to end of movie? Or will the software do this automatically?”

A VOB file is a video object file, which are the videos that are ripped from DVDs. A VOB cannot be more than 1 GB in size due to technical limitations of the DVD format. This isn't a problem when watching the movie on a DVD, but it can be a hassle when trying to convert the DVD to another video format.
