What is a .DMT file?
The .DMT file extension stands for a DeLorme Transfer File. This type of file is specifically created by mapping software products made by DeLorme, like Topo North America. When you work on a mapping project in these DeLorme software programs, you might save your work as a .TPX file, which is the standard project file. However, if you want to share your mapping project with others easily, you can package it into a .DMT file. This bundles everything into one single file, making it simpler to send via email or share online with friends, colleagues, or other users who might be interested in your mapping project.
To open a .DMT file, you would typically use the DeLorme Topo North America software. However, it's important to note that this software has been discontinued, which means it might be harder to find or use if you don't already have it installed on your computer. If you do have DeLorme Topo North America and you want to work with a .DMT file someone has shared with you, you can import it into the software. To do this, you would open the program, go to the "File" menu, select "Transfer," and then choose "Import." From there, you can navigate to the location of the .DMT file on your computer and open it to view or edit the mapping project inside.
