An ISO image (International Organization for Standardization) is an archive file (also known as a disc image) of an optical disc, composed of the data contents of every written sector of an optical disc, including the optical disc file system. They are stored in an uncompressed format. Any CD or DVD can be archived by .ISO format. It is a true digital copy of the original.
There are a number of freewares available to make ISO image from folders/CD-DVD. I happened to come across this easy to use software . It can be used in 3 simple steps:
- Start Free ISO Creator, Click “Options” to choose the file system you want to use
- Click “Add File(s)” button to add files or folders to the list.
- Select ISO Path (destination folder) to create ISO image file.
