How To Open ISO Archive

An ISO file is what’s called a disc backup – an exact copy of a CD or a DVD disc. ISO images are typically created as CD backups, but they can also be made “from scratch” using a specialized editor like WinISO. An ISO archive can only store a single track of data, so it doesn’t work for music CDs and a few more arcane CD types.

It may help to think of the .iso file like a kind of archive because it usually contains a number of files and folders. However, unlike other archives (e.g. ZIP or RAR), the ISO format stores everything in uncompressed form. Some commercial disc image formats like the UIF format and .daa file also support file compression.

To extract an ISO archive you will need to install one of the many ISO image tools. There’s a multitude of applications that can extract the ISO images, but most of them are either very expensive or simply lack any defining traits that would let you make an informed choice. So which one should you pick? Depending on your goal, there are two applications that I would recommend.

First, if you only need to extract the image, use 7-zip. It’s a free open-source archiver that can open ISO CD images. It will let you access the contents of the CD image, but that’s it – 7-zip can’t burn, mount or make new .iso images. It’s a neat and simple application and it supports Windows and Mac systems.

In case you need slightly more functionality you will probably want to get a fully-fetured ISO file application like PowerISO. Yes, it costs money, but it will let you do almost anything with an ISO or .uif files – extract it, modify, load it in a virtual drive, convert to a different format, and burn to a physical disc. PowerISO only works on Windows, though.

To summarize, ISO is a widely known, open DVD archive file that is supported by most CD applications. Some general-purpose archivers can also extract .iso files, but they generally can’t do anything else with them.
