An NZB file is a file format originally created by the guys over at newzbin.com An NZB file is simply a file that points to specific message or article IDs that act like a table contents for your newsreader or NZB client. This table of contents tells your NZB client or newsreader exactly where to find specific binary content you are looking for on the Usenet. For the geeks out there, an NZB file is actually an XML file format that contains the full message ID list for the binary content you are trying to download.
If you remember how binary files are stored on the Usenet, from our How The Usenet Works (Binaries section), each binary file is broken up into smaller compressed files (usually RAR format) along with PAR parity files to allow you to repair any missing parts after download. Theses smaller parts are spread across many Usenet messages or articles to make it possible to store the entire file on the Usenet. Because an NZB file points to all the parts that make up the file you wish to download, using NZBs to download files becomes the fastest and best way to download binary content from the Usenet.
To begin downloading binary content with NZBs right away, grab a Usenet account from our list of Recommended Usenet Providers, install an NZB client (List below), and begin searching for binary files using any of the most popular NZB sites (List to the left).
