File Extension NZB (.nzb files)

In order to use an NZB file, you must plug it into an nzb "client" program, which will then download the files listed in the NZB from your ISP's Usenet newsgroup server.

NZB files contain a plain-text listing of files and are interchangeable on all computers. Both of these NZB client programs run on Windows and the Macintosh:

SuperNZB (for power users)
ezNZB (for newbies)
