What is a CDP file?
Files with the .cdp file extension are most commonly used by the Trainz Simulator railroad games. These games allow players to create train simulations including train routes and locomotive designs. The CDP files contain add-on content that can be used in the game, providing players with additional routes, scenery, train designs and other game components.
The .cdp file extension is also used for SONY CD Architect project files, CA Visual Objects Platform for Developer files and CD/Spectrum Pro files.
