NZB - NewzBin Usenet Index File

What is a NZB file

NZB files are used by a service called NewzBin. NewzBin indexes content from Usenet servers and downloads the information needed for a special inquiry. NZB files contain information about posts made on Usenet, namely the name of the poster and the group the post was made in, file names and segments, and the unique ID of the posting itself. Since NZB are index files, they are used as such to gather information about the newsfeed content from a posting.

Stored in the XML format, NZB files help to save time and bandwidth when directing an inquiry to Usenet's NNTP servers. Instead of all headers available in a Usenet newsgroup, NZB files only contain the headers of a specific search. Thus, only the specifically searched for newsfeed and not the complete newsgroup list has to be updated. The NZB files themselves are XML-based text files.
