I have just downloaded what is supposed to be the movie open water. Instead of one or two movie file I have ended up with 49 files that are not recognised by any application. They are dvp-owa.r00 to dvp-owa.r47 inclusive and dvp-owa.rar and dvp-owa.sfv. I have never come across these file extensions before and don't know how to get them into a useable movie fromat. Can anyone help, Please.
