Copying iso

#1

I was trying to burn an iso to a cd using Roxio Easy Media Creator 9 and then ImgBurn. They wrote 3 files to the CD . I thought the Iso was to be writtten as one file?

Also ,on a 700MB CD, why does it need to be erased when 120MB is used? I had to erase the 120MB Roxio files to burn the 12oMB ImgBurn ones

  1. What’s in the ISO?

  2. You cannot burn DAO to a disc with existing data.
