NZB files were first created on the Usenet to speed up the downloading time for files. So what exactly is an nzb file? A file on the Usenet can be divided up into several parts. These parts are called ˜articles™ and your newsreader will recombine these articles for you once they are downloaded. Each article will have an ID number known as a message ID.
Every file has a completely unique message ID and it is from this ID that your newsreader knows which file to download. The nzb file is a multitude of message ID™s that mean that once you have imported it into your newsreader then the newsreader can download all at once.
The big advantage of these nzb files is that it speeds up the process and it does this because it does not download the headers in the file. Once you have your nzb file, you need to import it into your newsreader in order to open it. The newsreader will open it and download all the parts and assemble them for you. Fantastic! This saves loads of work which people used to have to do before the nzb files were invented.
The nzb file itself is a text file and if you really wanted to open it you could and you would see that it includes all the codes that we have talked about. They would not really be of much use to you without a newsreader as it will do the crucial part of retrieving the information and assembling the files for you.
All nzb files will have the extension .nzb on the end. Once you have the nzb file that you want, open it in your newsreader. Your newsreader will then located the file ID and start to download them. Once the downloads are complete, the newsreader will then automatically check that the files are not damaged and then assemble them for viewing.

You can then extract them from your newsreader and save them onto a disk or hard drive. The speed with which all this is done is dependent on your connection and your newsreader service, but it will be much faster than the internet offers you. The crucial part of an nzb is the newsreader, as the nzb file really is of no use without it. When you open the file without the newsreader, the information will not be comprehendible and certainly not the great movie of music file that you were hoping to see.
