What is ".nfo"

.nfo (also written .NFO or NFO, a contraction of "info", or " information") is a commonly used three-letter filename extension for text files that accompany various digital scene releases with information about them.

NFO files are used to deliver release information about the media, such as the digital media title, authorship, year, or licence information. This information is delivered for publishing the digital media to make it searchable on the web as well as within local catalogues and libraries.
