Some downloaded video games and applications have install and other kinds of instructions written down in .nfo or .diz files. Modern text editors are capable of opening files with this format.However, if you're interested in a straightforward NFO and DIZ viewer, you can take a look at DOS Viewer. It can be easily used by anyone. As the name suggests, the program is wrapped in a command-line interface, ideal for users who want to avoid the unnecessary visual elements that come with a graphical interface.

Furthermore, there is no installation necessary since it's possible to unzip the downloaded archive and double-click the .exe to reach the main app window right away. You can also keep the tool stored on your USB flash drive to be able to run it on any PC without setup.Once you have the main window in front, you can open files with the DIZ and NFO type.

There are no kind of editing features available, so DOS Viewer can be used for reading purposes only.
