How to Burn ISO Files Larger Than 4.7 GB
If you have a piece of software in ISO format and it's too large to fit on a standard blank DVD, burn the image on a dual-layer disc. ISO images need to be burned on a single disc in ISO format to be recognized as disc images for software installation or live-disc booting. Blank dual-layer DVDs hold up to 8.5 GB and work with image-burning software the same way as single-layer discs. You won't need to configure the ISO-burning project any special way to burn a dual-layer disc.
