NZB
XML-based file format
From Wikipedia, the free encyclopedia
NZB is an XML-based file format for retrieving posts from NNTP (Usenet) servers.[4] The format was conceived by the developers of the Newzbin.com 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 called the "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 or Uuencode).[12]
