SuperNZB

SuperNZB is a tool created to help you download large NZB files onto your computer without any special effort using the Usenet system.
The application is made to be simple to use and comprehensive. You do get this feeling the moment you run it for the first time as you are greeted with a window that helps you understand how to download NZB files, how to extract them from RAR archives, how to repair damaged items with PAR files and how to verify them with SFV. Not to mention that you get help and explanations along the entire use of the application which makes it a very good choice even for beginners.
SuperNZB displays a user-friendly interface which most parts is self explanatory. The application can’t find NZB files for you so you have to search for them on NZB-Indexing web sites. It also features a RAR decoder and a SFV file checker. As a download manager it also provides you with a queue, stats, decodes for PAR and RAR formats, as well as job manager for them.
To download the files, all you have to do is find them on a newsgroup server, enter its URL, username and password. Since Usenet doesn't offer automatic error correction, NZB files generally contain PAR documents that help you repair other files which are damaged during download and SuperNZB makes use of an unPARing feature. The application also features a RAR decoder that helps you unpack the archived files.
The archives you need are separated into more smaller ones while downloading and the application displays the server status, if any errors occur, the archive size, download speed and progress. You also get stats that inform you of the combined speed, peak and the estimated time left.
In conclusion SuperNZB is a reliable, fast and practical application you can use to download NZB files.
