I'm trying to make a backup copy of excite truck. I downloaded the file through a torrent. I tried extracting just one of the files and then burning the ISO image with DVD descriptor for when I selected my source file I got in a message that said something like "invalid or unexpected image format. Then I tried to extract all the files and burn them with DVD decryptor but I got the same error message. I am new to the whole RAR idea I'm not even sure I was extracting the current files. The first file I have has a.RAR extension and the rest have a .r00 .r01 .r02 etc. I'm using winrar and not all of the files say winrar archive under the type column. some just say r30 etc. I also have a .nfo file as well as a.svf file please help.
