How to open CDP file?

The most common problem when using Trainz Simulator Content Dispatcher Pack is that a specific CDP is not associated with the program. This is manifested by the fact that CDP files open in unusual applications or do not have an assigned program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the CDP file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Trainz Classics

In this case, you should first verify that the Trainz Classics application is installed on the computer. The easiest method is to use the system search engine by entering the program name Trainz Classics in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open CDP files.

Programs to open CDP file

Remember to download programs supporting CDP files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Trainz Classics with CDP files

However, it may happen that the application itself does not cause the CDP file to open in the Trainz Classics application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the Trainz Classics application as the default for handling the CDP file.

Step 3. Update Trainz Classics to the latest version

The fault may also lie with the Trainz Classics program, it is possible that Trainz Simulator Content Dispatcher Pack requires a newer version of the program.

Step 4. Check for the following problems with the CDP file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The CDP file may be unusually small compared to the original file. This is most often caused by a problem while downloading the CDP file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the CDP file that we want to open. Sometimes virus-infected CDP files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the CDP file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular CDP file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted CDP files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the CDP file to another location.
This problem usually affects more complex files. In this case, the CDP file is blocked by the first application to open it. Just close unnecessary programs. Sometimes you have to wait for the session to the file CDP to close. Some anti-virus or backup software may occupy the CDP file for a certain period of time. If the problem persists, restart the machine.
