UltraISO is a CD image file creating/editing/converting tool; it can directly edit the CD image file and extract files and folders from it, as well as make ISO files from your CD-ROM or hard drive. At the same time, you can maintain the ISO bootable information, thus creating your own bootable CDs. With UltraISO, you now have the power to make and edit your own ISO files, and then burn them to CD for your own needs.
