What is DDP file?

The DDP file has been categorized as Developer Files. The author of this format is Embarcadero Technologies. In addition to this file, the Developer Files category includes 1205 related files. Delphi Diagram Portfolio Format appears on 1 operating systems as a functional file. These systems consist of Windows, although it may occasionally be found on another system, it will be non-functional.

How to open DDP file?

An often recurring problem with Delphi Diagram Portfolio Format is that DDP is not associated with the correct program file. This is manifested by the fact that DDP 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 DDP 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 Embarcadero Delphi

An often overlooked issue is to make sure that Embarcadero Delphi is installed on the computer. This can be achieved by typing Embarcadero Delphi into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support DDP files.

Programs to open DDP file

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

Step 2. Create association of Embarcadero Delphi with DDP files

However, it may happen that the application itself does not cause the DDP file to open in the Embarcadero Delphi application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. 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 Embarcadero Delphi application as the default for handling the DDP file.

Step 3. Update Embarcadero Delphi to the latest version

The fault may also lie with the Embarcadero Delphi program, it is possible that Delphi Diagram Portfolio Format requires a newer version of the program.

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

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the DDP file. The only repair option is to download the file again.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file DDP or the program directory. However, remember that not every infected DDP file can be recovered, so it is important to take care of regular backups.
Older version of DDP file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair DDP file corruption.
When reading, a message appears that the file was encrypted or corrupted. The encrypted DDP files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the DDP file to another location.
This can happen on a file that does not support multiple access. In this case, the DDP file is blocked by the first application to open it. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. However, some background programs may block the DDP file while scanning. If this does not work either, restart the device.
