Files that contain the .dxr file extension are most commonly associated with the Macromedia Director software application. The DXR files that are used by this software program contain Director movie files that have been stored in a non-editable file format. This allows a user to share and distribute a Director file without allowing other users to make edits or modifications to it.
The DXR files are saved in an uncompressed format. Macromedia developed the DXR file format, but the company was taken over by Adobe in 2005. The current version of Director is published by Adobe and not by Macromedia.
