What UltraISO is
UltraISO is a Windows utility for creating, editing, extracting, and converting CD/DVD image files. It handles ISO, BIN, IMG, NRG, MDS, CCD, ISZ, DMG, DAA, UIF, and HFS formats, and converts image files to ISO. Boot features preserve boot information when creating images and let you add, remove, or extract an ISO boot image. Its revision history lists AutoSplit for writing a bootable UEFI USB disk from a Windows 10 ISO. Windows shell integration lets you open images by double-clicking or using the right-click menu. Command-line parameters cover creating, converting, extracting, and checking images. The FAQ states a maximum ISO size of 2TB (2000GB). The unregistered version has a 300MB document limit and a startup dialogue; registration removes both. UltraISO costs $29.95, paid once, with a free trial available. Registered users receive lifetime free updates and free email technical support. Listed requirements include Windows 10 and older versions through Windows NT 4.0 SP6a+.
