XML-based file format

NZB file format Filename extension .nzb[1] Internet media type application/x-nzb Developed by NewzBin[2] Latest release 1.1 November 10, 2009; 16 years ago (2009-11-10) Type of format Usenet extender Extended from XML Open format? yes Website NZB file specification[3]

**NZB** is an [XML](/source/XML)-based file format for retrieving posts from [NNTP](/source/NNTP) ([Usenet](/source/Usenet)) servers.[4] The format was conceived by the developers of the [Newzbin.com](/source/NewzBin) [Usenet](/source/Usenet) Index.[5][6] NZB is effective when used with search-capable websites.[7] These websites create NZB files out of what is needed to be downloaded.[8] Using this concept, headers would not be downloaded hence the NZB method is quicker and more bandwidth-efficient than traditional methods.[9]

Each Usenet message has a [unique identifier](/source/Unique_identifier) called the "[Message-ID](/source/Message-ID)".[10] 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.[11] 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](/source/YEnc) or [Uuencode](/source/Uuencode)).[12]
