  • Popularity

  • Category Text Files
  • Format Text

Plain text file that includes information about a pirated software program (warez); contains release notes and commonly includes information about the piracy group responsible for distributing the warez; generally included as part of the program and related files; first used in the late 1980s by a cracking group named The Humble Guys (THG).

NFO files often contain ASCII art identifying the piracy group. NFO readers such as NFOPad can render the text characters as the intended graphic. For standard text editors, it's generally best to view the text with a fixed width font.

NOTE: Since Microsoft Windows' System Information tool also uses the ".nfo" file extension, Windows may unsuccessfully try to open NFO files in the System Information viewer. Instead, open the files directly in a text editor or an NFO viewer.
