When a single ISO file, such as a Linux ISO file, is burned onto a CD / DVD and then you look at the contents of the CD / DVD afterwords, then the CD / DVD has lots of files on it, and not just a single file. When you burn a Linux ISO file to a CD / DVD, then the CD / DVD has all the Linux operating system program files that are needed on the CD / DVD (instead of a single file ending in .iso). Linux Tips: Always check the contents of a Linux CD / DVD after burning a Linux ISO. If you burn it incorrectly, then you will have a single file on the CD / DVD (ending in .iso) instead of the complete Linux OS (thousands of Linux software programs) on a "bootable" CD / DVD. Therefore, when you try to boot with this Linux CD / DVD, you won't be able to - and you won't be able to run Linux (and install Linux or run a Linux live version)! Some Linux versions just need a single CD / DVD and others need more than one CD / DVD. For example a Linux "live" version just requires a single CD / DVD and some Linux installation versions require more than one CD / DVD. So, if you're downloading some versions of Linux to burn on CD / DVD, so that you can install Linux from CD / DVD, then you may need to download several Linux ISO files and burn them to several CD / DVDs.
