A VOB file is generally stored in the “Video_TS” folder within the DVD file. It comprises audio, video, subtitles, DVD menus, among other components. These files are formatted as “MPEG-2” system streams. You can access VOB files on video playback applications like Media Players.

WMV stands for Windows Media Video, which is a video stored in the Microsoft Advanced Systems Format (ASF) and is compressed with the WMV compression criteria. WMV files are mostly encrypted with DRM protection. You can play them in Microsoft media players.
