What is NZB file?

NewzBin Usenet Index Format is supported by 3 operating systems. The file will work on Linux, Mac OS, Windows systems, unfortunately not on others.

How to open NZB file?

The most common problem when using NewzBin Usenet Index Format is that a specific NZB is not associated with the program. This is manifested by the fact that NZB files open in unusual applications or do not have an assigned program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the NZB file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Unison

An often overlooked issue is to make sure that Unison is installed on the computer. To do this, enter the name Unison into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file NZB with Unison. Below you will find a list of applications that support NZB files.

Step 2. Create association of Unison with NZB files

However, it may happen that the application itself does not cause the NZB file to open in the Unison application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the NZB file with the Unison program.

Step 3. Update Unison to the latest version

If, however, after binding Unison with NewzBin Usenet Index Format there were still problems, you should update the program to the latest version.

Step 4. Check for the following problems with the NZB file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the NZB file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the NZB file that we want to open. However, remember that not every infected NZB file can be recovered, so it is important to take care of regular backups.
Older version of NZB file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular NZB file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted file NZB except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. Copying the NZB file to another location will fix the problem.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the NZB file for a certain period of time. If the problem persists, restart the machine.
