An ISO File, is an basically image of a DVD, or CD. This File is not what is put onto a CD or DVD, but contains the files that are. Consider it as a ZIP file. If you've ever explored the contents of a DVD movie on your PC's DVD drive, you will have seen something like this; two folders, VIDEO_TS and AUDIO_TS. The VIDEO_TS folder contains all the compressed video and sound files, as well as the information that allows the player to access them in proper order. The AUDIO_TS folder is used for DVD-audio disks and is left empty for DVD-video, though it is always included for compatibility reasons. The contents of a typical VIDEO_TS folder will resemble this: Therefore; DVD files end in .VOB .BUP and .IFO Hope this helps!
