My father wants to burn a bunch of pictures to CD's and instead of data cd's, he somehow managed to save it all as ISO cd's. Now when he wants to burn he gets asked to insurt a previously made medium. Personally i have no idea what that is or how to burn it, so i tried to change all the files to normal data files, but i don't know how, so so far i've only tried various options and found no solution and copying the files and trying to paste them into an open data disc creator also doesn't work, because the formats are different. The problem is that those pictures were assembled from various folders and it took 3 or 4 hours for the whole job and my father refuses to do it again. Is there any way to convert those files, saved to be burned as ISO images, to normal data files? I would be very thankful if i got any help.
