Opening DT2 files
Did your computer fail to open a DT2 file? We explain what DT2 files are and recommend software that we know can open or convert your DT2 files.
What is a DT2 file?
Files that contain the .dt2 file extension are created by the Microsoft Live Messenger application. The files with the .dt2 file extension contain the Microsoft Live Messenger avatar images and emoticons. The DT2 files are actually PNG files, but these files have been renamed with the .dt2 file extension for use within the IM application.
The .dt2 file extension is also given to military files that have been created by the Digital Terrain Elevation Data program. These files are created by the National Imagery and Mapping Agency and contain information about the terrain of the areas that have been mapped.
Software that will open, convert or fix DT2 files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
