How to open ONM file?

An often recurring problem with Outdoor Navigator Map is that ONM is not associated with the correct program file. This is manifested by the fact that ONM 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 ONM 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 Outdoor Navigator

If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support ONM files.

Programs to open ONM file

Remember to download programs supporting ONM files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Outdoor Navigator with ONM files

If, despite the installed application, the ONM file does not start in the Outdoor Navigator application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select 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. 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 ONM file with the Outdoor Navigator application.

Step 3. Update Outdoor Navigator to the latest version

The fault may also lie with the Outdoor Navigator program, it is possible that Outdoor Navigator Map requires a newer version of the program. This can be done using the application (if it provides such options) or from the Maptech, Inc. website and install the latest version.

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

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. Usually this applies to ONM files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the ONM file that we want to open. Sometimes virus-infected ONM files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the ONM file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair ONM file corruption. You can restore the file from a backup or use Maptech, Inc. help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted ONM files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. Copying the ONM file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file ONM to close. Some anti-virus or backup software may occupy the ONM file for a certain period of time. If this does not work either, restart the device.
