File Extensions - DIZ and NFO File Formats

SUMMARY: Description files .DIZ and .NFO defined.

The DIZ and NFO file extensions, most used in files named filename.diz and readme.nfo, represent text files most commonly used in the bulletin board days that preceded the Internet. These files were used to describe the contents of ZIP archives. Though not commonly used today, you can still sometimes see them when downloading files from certain websites.

Windows users: NOTE that unless you have configured your computer with the file extension viewing tweak, it is possible that a filename that looks like it ends with ".diz" or ".nfo", especially one attached to an e-mail message, actually has a hidden OTHER extension, meaning that if you double-click the file, it may actually run a computer virus!
