DMT File
Did your computer fail to open a DMT file? We explain what they are used for and recommend software that we know can open or otherwise handle your .DMT files.
What is a DMT file?
A .DMT file is a DeLorme Street Atlas Map Transfer file. .dmt files are files used in DeLorme Street Atlas Map, a navigation software used in travel and deliveries. The .dmt files contain data that users can transfer to another device, such as a computer using the DeLorme Street Atlas Map. This software is obsolete and DeLorme has been acquired by Garmin.

What else are .DMT files used for?

The DMT file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a DMT opener may not be able to open all kinds of DMT files. In this case, look through both formats to make sure you find the best suited DMT viewer.
