How to burn ISO files larger than 4.7 gb
Burn large ISO files on dual-layer DVDs. (Jupiterimages/ Images)

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 burnt on a single disc in ISO format to be recognised 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.

Skill level:

Things you need

  • Blank dual-layer DVDs
  • Dual-layer-compatible DVD burner
