cd/dvd search

Is it possible to look on cd/dvd media for lost files?

As in.. what if you incidentally (yes, laugh.. but it happened to me) quickerase a dvd, but want to recover the old files?

I've tried isobuster and was able to create a file from the disk that contains EVERYTHING, but can't take my files out of that, altho it sees a lot of them...

Would it also be possible to extract files from files like that?

More info on this..: http://www.isobuster.com/tips.php?tips_page=9

(sheds a little light on the situation, but.. still want to know IF files could be substracted from a file created by isobuster. I believe it's an ISO file or NFO or something, so...)

Great idea, we'll look into whether this is possible or not.
