DEM stands for Demo. A number of video games use .DEM file extension to provide a demo of the game. The file mostly contains in-game recordings which are used to show the users about the gameplay of the video game.
There are different software applications available for opening .DEM files and in some software applications you can play the .DEM file and record it to different video output formats. There are other .DEM files also so make sure that you have the right .DEM file while opening.
We hope we helped you solve the problem with the DEM file.

There can be more reasons which determine that you are not able to open the DEM file (apart from the lack of the proper application installed).
First - the DEM file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the DEM file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the DEM file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the DEM file has not been completed and it cannot be opened properly).
