NFO files are small data bits that accompany most warez scene releases of pirated software or media. They contain information about the title, author, license, encoding type, and more. These files cannot be opened correctly using common text viewers, instead you need a dedicated NFO file viewing tool like iNFekt.

DAMN NFO Viewer is a lightweight freeware specially designed for viewing (not editing) NFO (*.nfo) and DIZ (*.diz) files.
