NZB Download Checker

NZB Download Checker is a software application that checks an NZB for you, so that you can see if the files you may be interested in downloading actually exist in Usenet.
NZB is a file format derived from XML (Extensible Markup Language – defines a set of rules from encoding documents in a format that is both human and machine readable) and its main use is to retrieve posts from Usenet servers (NNTP). Usually, websites that have search capabilities create NZB files out of what is needed to be downloaded. This method is considered to be much faster and bandwidth-efficient.
NZB Download Checker has a very simple and outdated interface, resembling the classical design that was adopted in Windows ’98. Despite all that, the UI is intuitive and therefore easy to use, at least to individuals that know a little bit about IT. Most people are not actually able to use this software program, not because of the interface, but due to lack of knowledge.
Every file that exists on Usenet is split into many parts and each and every one of them has its own unique number, also known as Message ID. NZB Download Checker sends all the Message IDs listed in an NZB file to your news server(s) and checks the replies. Basically, this software program helps you find out how much of the data you are interested in exists, without actually downloading anything. This way, you save a lot of time and resources.
All in all, NZB Download Checker is a handy tool that you can use to check if certain files exist on Usenet servers. Although the interface is intuitive and simple, this is mostly a utility that is used by people with extensive IT knowledge.
