UltraISO is an all-in-one solution to all your ISO-related needs. With this versatile tool you can create, edit, burn, extract, and even change the format of your ISO files. You may delete or add new files to the ISO file and change its volume name without extracting the files and building a new image. Its burning capabilities include support of all types of recordable discs of any storage capacity, from a 185 MB CD-R to a 50 GB BluRay disc.

ISO files are gaining more and more popularity by the hour. They are extensively used to clone all types of discs, as they preserve all the information and the folder structure of the original set of files. Besides, they can be easily stored and re-used to burn new 1:1 copies of the original disc as many times as required. The problem is that ISO files need to be “broken” to be edited or to view its content. This is where UltraISO comes in. This neat application allows you to handle an ISO file as if it is a folder on your system – you can open it and browse its files and folders, delete some and add new ones, edit its files, play back whatever media they contain (a film on a DVD, music tracks, etc.), and all of this without extracting its contents. It’s like playing around with the contents of a ZIP file without unzipping it (actually, image files and archive files have a lot in common).

UltraISO can “mount” your ISO files on a virtual drive. This means that it allows you to work with the contents of your ISO file just as if you had just burnt it to disc and put it on one of your disc drives, except for the fact that your ISO file remains intact.

The program comes with some interesting “extra” tools. It allows you to verify the integrity of your ISO files and discs using Checksums, check their contents, test them, compress them to save space, etc. Another very important section of the program is devoted to bootable discs. Here you can build, write, and burn disk images, extract boot files from discs, generate Bootinfotables, load boot files, etc.

Few ISO tools are as comprehensive as UltraISO. Though it has some limitations, I recommend you to check its trial version and see how flexible an ISO file can be.
