- The quick facts

What are NZB files and how to open them

Are you having problems opening a NZB file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is a NZB file?

A .NZB file is a Newzbin Usenet Index file.

The Newzbin indexing service uses files that contain the .nzb file extension. Newzbin indexes the contents of a Usenet posting, such as the poster name, posting groups, file names, and a unique ID.

An NZB file can be used to gather the contents of a news feed from a Usenet posting. The NZB file will do this by downloading headers that are specific to a user's search criteria rather than downloading all of the headers in a particular newsgroup. NZB files are saved in the XML file format. This allows users to save bandwidth and time since the entire newsgroup list does not have to be updated while the files are being downloaded onto the user's computer.
