Troubleshoot DDP Files


Troubles Opening DDP Files

Missing Delphi (IDE)

When you double-click your DDP file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". When this happens, it is commonly due to Delphi (IDE) missing in %%os%%. The typical path of opening your DDP with a double-click won't work because %%os%% cannot make the program connection.


Tip: If you have another software that you know opens DDP files, you can select it by hitting the "Show Apps" button.


Delphi (IDE) is Out-of-Date

It is possible that your version of Delphi (IDE) isn't able to open your Delphi Diagram Portfolio File file due to incompatibility. Visit the Embarcadero Technologies website to download (or purchase) the latest version of Delphi (IDE). Most of the time your Delphi Diagram Portfolio File file was created by a newer Delphi (IDE) than what you have installed.


Tip: Investigate your DDP file by right-clicking and selecting "Properties" to find clues on what version you need.


Conclusion: The majority of DDP file opening issues are due to not having the correct Delphi (IDE) version installed.


Other Causes of DDP File Opening Problems

In the majority of cases, installing the right version of Delphi (IDE) will resolve your issue. If you are continuing to have errors with loading DDP files, other external issues might be to blame. These other problems include (listed in order from most to least common):

  • DDP file references in the Windows Registry are broken
  • Unintentional removal of the description of the DDP file inside the Windows Registry
  • Partial installation of Delphi (IDE) that did not fully complete
  • Something has caused file corruption of your DDP
  • Malware-tainted DDP file can't be opened
  • Drivers associated with DDP software need to be updated
  • Too many applications are open on your PC to load your Delphi Diagram Portfolio File file successfully
