I have an iso file that I can't open. If I try to open it in PowerIso I get the invalid or unsupported box. I have tried ImgBurn, PowerIso, Nero, etc. ImgBurn & Nero will actually take the file and "burn" it to disk - the process looks normal as the programs read the file and take the usual amount of time to be burning the disk, drive light flashes on / off as normal, but when the session is complete there is no data on the disk, physically there is only what looks like a header. How can the program be "burning" the disk but not actually doing it? What can I use to verify that the file is usable in the first place? Then how can I get the file to burn to disk? or better yet, how can I just open the file without burning to disk so that I can extract the files to hard drive?
