What is a LMX file?

The LMX file extension is linked to Landmark Exchange Format and belongs to the GIS Files category, which includes 247 files.

The Landmark Exchange Format (LMX) was developed by Nokia, which created file format and 7 programs to work with them.

LMX file support extends to various operating systems, including Windows, Mac OS and Linux, as well as mobile devices running Android. To open a LMX file, you can choose from 3 programs such as Route 66, GPSBabel and Nokia Suite.

How to open a LMX file?

If you cannot open a LMX file, it is most often due to missing software. Select a program from the list according to your operating system. Then go to the official website of the program developer, download it, and install it on your device.

When it comes to opening and working with LMX files, Route 66, GPSBabel and Nokia Suite are the top choices for users. To install the updated version of Route 66, simply go to the ROUTE 66 site and download the installer compatible with all major platforms.

Once installed, Route 66 will be set as the default program, and LMX files will open automatically.

Set Route 66 as the default LMX program

Changing Default Programs in Windows

  1. Right click on your LMX file, then select "Open with" and click "Choose another application";
  2. In the pop-up window, select the Route 66 application;
  3. Check the "Always use this application" checkbox, and then click "OK" to apply the selected application as the default for opening LMX files.

Change Default Program on Mac

  1. Right click or Control + left click on the desired LMX file;
  2. Select "Open in application" and click "Other";
  3. At the bottom of the window, find the "Enable" menu, where "Recommended Programs" is already selected by default;
  4. Within this menu, select "All Programs" and then locate Route 66. Check the box next to "Always open in app" to set it as the default program.

Convert to and from LMX

Keep in mind that converting a LMX file may introduce some limitations, but the original format can often be restored.

Offline software like GPSBabel allows you to convert LMX files to other formats while maintaining quality.

Solve problems with LMX files

Certain problems with LMX files can be conveniently fixed with small software tweaks. Here are some helpful tips to address them.

Why does Route 66 stop responding or crash intermittently?

The likely cause of Route 66 crashing is lack of software updates. Install the latest updates available for ROUTE 66 products.

Restarting your computer will solve many common problems, which is why it’s the first thing you should do before changing any settings related to the software.

What are the best practices for repairing a LMX file that has gone bad?

Open the corrupted LMX file in a recovery program and select the "Repair" menu item. Please be patient while the recovery process completes, which will automatically restore the damaged gis files.

How do I know if my LMX file is corrupted?

Common indications of damaged LMX gis files are:

  • Attempts to open the file result in errors or failed results;
  • The file causes Route 66 or other programs to hang or crash during operation;
  • Unexplained increase in LMX file size;
  • Error messages appear while working with the file;
