How to Create an ISO File

Attention Before you read this tutorial, I highly recommend you check out my resources page for access to the tools and services I use to not only maintain my system but also fix all my computer errors, by clicking here!

An ISO file or ISO image, depending on which term you prefer to use is an archive file typically made from an optical disc, although it can be made from files and folders on your hard drive. ISO files in most cases have the .ISO file extension, which was taken from the old ISO 9660 file system that was used for the original CD-ROM media. Despite being named after that old file system, these files use a variety of file systems to package data.

The process of creating these ISO files is fairly simple, providing you use the appropriate software to do the job. There are a variety of programs that you can use to make these files, but PowerISO, is amongst the most popular, as it enables users to be able to create images from CD/DVD and the content on their computers. You can also do a variety of other things, such as encrypt, compress and extract an ISO image.

Creating an ISO file from content on your computer is, in most cases a point and click affair. However, the exact process usually depends on the application you’re using.

Once you’ve created your image, it’s also possible for you to make alterations to it. This can be done in the form of adding or removing existing files, a process which should entail nothing more than dragging and dropping files. Of course, functions such as this are not available on every single ISO maker application, so that’s one thing you’ll need to be cognizant of.

Another thing that you should be aware of is the fact that it’s possible to find ISO files in a number of different formats, such as the .BIN and .DAA file extension, all of which are similar in virtually every way to an .ISO file.

Advantages of Using ISO Files

There are a number of benefits to ISO files, but the main ones are as follows:

  • When you convert the contents of a CD/DVD to an ISO file, an exact replica is made of it. This includes the header data, which means no information is lost during the conversion process.
  • Using a virtual drive, ISO files can be mounted, enabling them to function as if they were real CD/DVDs.
  • When you convert your files and folders to an ISO image, they are given the added advantage of being protected by any virus that may/could infect your machine.

Software for Creating ISO Files

There are quite a few programs available online that you can use to convert your data to an ISO files. The following are amongst the most sought after:

  • Roxio Easy CD Creator: This program is one function of the Roxio Creator digital media suite. Creating ISO files with it is a relatively simple process; however, you’ll need to purchase the Roxio Creator in order to access it.
  • Nero – Burning ROM: This application is similar to the Roxio Creator, in that it’s a complete digital media suite. You’ll have to purchase it before you can use it to convert your CD/DVD to ISO images.
  • PowerISO: This application is made available as both a freeware and paid product. The free version comes with all the features that you’ll need to create ISO files from both CD/DVD and your computer files/folders.

The first two applications will enable you to convert data to ISO format, but do not provide you with any editable functionality. PowerISO on the other hand enables the user to be able to both remove, and add files to existing ISO images. That is why I recommend PowerISO, as it not only has an expansive feature set, but it’s also made available for free.

If you would like to know how to create an ISO file from a CD/DVD or files and folders on your computer, then I suggest you continue reading.
