WinISO is a powerful and easy-to-use tool that allows users to create, edit, and extract ISO files. ISO files are a type of disk image file that contains the contents of an optical disc, such as a CD, DVD, or Blu-ray disc. These files are widely used for distributing software, games, and operating systems over the internet. With WinISO, users can directly access and modify the contents of an ISO file without needing to burn it onto a physical disc.
