What is a .TPX file?
The .TPX file extension is used for a project file created by a program called DeLorme Topo North America. This program was designed for making maps. When you create a map using DeLorme Topo North America, it saves all the work you've done in a file that ends with .TPX. This file can include a lot of different things like pictures from above the ground (aerial imagery), places that are interesting or important (points of interest), and other information that helps make the map more useful.
However, it's important to know that DeLorme Topo North America is no longer being made or updated, which means it has been discontinued. This could make it a bit tricky to open .TPX files if you don't already have DeLorme Topo North America installed on your computer.
If you want to share the maps you've made with other people who use Topo NA, you can put your .TPX file into another type of file called .DMT. This makes it easier to share your maps with others who have the same interest in mapping. Since DeLorme Topo North America is discontinued, finding alternative ways to open or convert .TPX files might require some research or asking for help from communities interested in mapping software.
Verification
Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files. If you want to suggest edits or updates about .TPX file formats, example files, or programs that are compatible. Please contact us.
