Opening NZB files

Did your computer fail to open a NZB file? We explain what NZB files are and recommend software that we know can open or convert your NZB files.

What is a NZB file?

Files that contain the .nzb file extension are used by the Newzbin indexing service. Newzbin indexes the contents of a Usenet posting, such as the poster name, posting groups, file names and 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.
