Actually each iso is singular, but in instances where you download multiple isos that make up a package (whether or not the secondary, tertiary, etc images contain ancillary or spurious files), how do commit such a mess to (singular) bootable media, such as a thumb drive? You can use rufus or any number of other utilities to "burn" the image into a bootable format. But what about the subsequent isos? Simply unpack them and load them onto the bootable media?
