What is TNR file?

The file with the extension TNR is the System Files file type. The author of this format is Trimble Navigation Limited. In addition to this file, the System Files category includes 323 related files. GPS Pathfinder ProXR/XRS Firmware is most often found on 1 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. The main program that supports this format is GPS Pathfinder Office. This was created by Trimble Navigation Limited.

How to open TNR file?

The main problem with GPS Pathfinder ProXR/XRS Firmware is that the TNR file is incorrectly associated with programs. This causes the file TNR 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 TNR 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 GPS Pathfinder Office

An often overlooked issue is to make sure that GPS Pathfinder Office is installed on the computer. The easiest method is to use the system search engine by entering the program name GPS Pathfinder Office in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file TNR.

Programs to open TNR file

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

Step 2. Create association of GPS Pathfinder Office with TNR files

If, despite the installed application, the TNR file does not start in the GPS Pathfinder Office application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the TNR file with the GPS Pathfinder Office application.

Step 3. Update GPS Pathfinder Office to the latest version

If, despite the association of the GPS Pathfinder Office program with the GPS Pathfinder ProXR/XRS Firmware file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Trimble Navigation Limited website and install the latest version.

Step 4. Check for the following problems with the TNR 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:

Very often, the file may be size 0 or incomplete. Usually this applies to TNR 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 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 TNR file that we want to open. Sometimes virus-infected TNR files cannot be recovered, so make a backup in advance.
Older version of TNR file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair TNR file corruption. You can restore the file from a backup or use Trimble Navigation Limited help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted TNR 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 of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. Copying the TNR 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. Sometimes you have to wait for the session to the file TNR to close. However, some background programs may block the TNR file while scanning. If the problem persists, restart the machine.
