'''NZB''' is an [[XML]]-based file format for retrieving posts from [[NNTP]] ([[Usenet]]) servers.<ref>{{Cite web|url=http://www.techsono.com/usenet/faq/nzb|title=NZB Files Explained in Plain English|accessdate=2020-01-24}}</ref> The format was conceived by the developers of the [[NewzBin|Newzbin.com]] [[Usenet]] Index.<ref>{{Cite web|url=https://www.nzb.fi/2005/08/nzb-01-released/|title=nzb 0.1 Released « nzb|accessdate=2020-01-24}}</ref><ref>{{Cite web|url=http://powerpost.free.fr/|title=Power-Post-2000-A&A|website=powerpost.free.fr|accessdate=2020-01-24|date=2004-03-21}}</ref> NZB is effective when used with search-capable websites.<ref>{{Cite web|url=https://www.binaries4all.com/nzb/|title=Tutorial: What is NZB? What are NZB files? |website=Binaries4all Usenet Tutorials|accessdate=2020-01-24}}</ref> These websites create NZB files out of what is needed to be downloaded.<ref>{{Cite web|url=http://www.wisegeek.com/what-is-an-nzb-file.htm|title=What is an NZB File? (with picture)|website=wiseGEEK|accessdate=2020-01-24}}</ref> Using this concept, headers would not be downloaded hence the NZB method is quicker and more bandwidth-efficient than traditional methods.<ref>{{Cite web|url=http://newsleecher.com/forum/viewtopic.php?t=2503|title=Select download folder when using NZB?|website=NewsLeecher Forums|accessdate=2020-01-24|date=2004-09-11}}</ref>

Each Usenet message has a [[unique identifier]] called the "[[Message-ID]]".<ref>{{Cite web|url=https://www.binaries4all.nl/nzb/|title=Handleiding: Wat zijn NZB-bestanden? Wat is NZB?|website=binaries4all.nl|accessdate=2020-01-24}}</ref>  When a large file is posted to a Usenet newsgroup, it is usually divided into multiple messages (called segments or parts) each having its own Message-ID.<ref>{{Cite web|url=http://docs.newzbin.com/index.php?pagename=WhatIsAnNZBFile|archive-url=https://web.archive.org/web/20040504002459/http://docs.newzbin.com/index.php?pagename=WhatIsAnNZBFile|url-status=dead|archive-date=2004-05-04|title=NBDocs - What Is An NZB File|date=2004-05-04|accessdate=2020-01-24}}</ref> An NZB-capable Usenet client will read all needed Message-IDs from the NZB file, download them and decode the messages back into a binary file (usually using [[yEnc]] or [[Uuencode]]).<ref>{{Cite web|url=https://sourceforge.net/projects/nzb/files/nzb/0.1/|title=nzb - Browse /nzb/0.1 |website=SourceForge.net|accessdate=2020-01-24}}</ref>
