How to Convert a File or Folder to an ISO in Windows 10/11

An ISO file is a container, usually derived from a CD or DVD’s contents, that can hold a decent number of files. Though creating CD and DVD backups is its typical function, an ISO can also be created from files and folders already on your Windows computer.
