Opening DEM files
Did your computer fail to open a DEM file? We explain what DEM files are and recommend software that we know can open or convert your DEM files.
What is a DEM file?
Files that contain the .dem file extension are most commonly associated with video game demo files.
A variety of commercial video games use the DEM file format for demonstration purposes. These files normally contain in-game recordings that show users an example of the associated video game.
Popular video games that use the .dem file extension include Unreal Tournament, Half-Life and Quake.
The .dem file extension is also used for a variety of 3D graphic files, such as those create by Vista Pro and ArcView.
The .dem file suffix is also used by the iGO software application. These DEM files contain elevation model files that are used by the software program.
Software that will open, convert or fix DEM 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.
