How to open NM3 file?

The main problem with Navitel 5 Map Format is that the NM3 file is incorrectly associated with programs. This causes the file NM3 to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the NM3 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 Navitel Navigator

An often overlooked issue is to make sure that Navitel Navigator is installed on the computer. The easiest method is to use the system search engine by entering the program name Navitel Navigator in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file NM3 with Navitel Navigator. Later in this article you will find a list of programs that can open NM3 files.

Step 2. Create association of Navitel Navigator with NM3 files

If, despite the installed application, the NM3 file does not start in the Navitel Navigator application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the NM3 file with the Navitel Navigator application.

Step 3. Update Navitel Navigator to the latest version

If, however, after binding Navitel Navigator with Navitel 5 Map Format there were still problems, you should update the program to the latest version.

Step 4. Check for the following problems with the NM3 file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

The NM3 file may be unusually small compared to the original file. This is most often caused by a problem while downloading the NM3 file. The only repair option is to download the file again.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the NM3 file that we want to open. Sometimes virus-infected NM3 files cannot be recovered, so make a backup in advance.
Older version of NM3 file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair NM3 file corruption.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file NM3 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. Copying the NM3 file to another location will fix the problem.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
