Opening a DDP File

The DDP file type is primarily associated with Delphi.

What is a DDP file?

DDP files mostly belong to Delphi by Embarcadero. A DDP file is a diagram portfolio created by some versions of Delphi integrated development environment for building Delphi applications. Another type of DDP file contains parameters (settings) which DDAdd uses to protect Dinkey Dongles. A Dinkey Dongle protects data stored on USB disks. DDP is also the filename extension of a design project created with DreamPlan Home Design. Such a project contains the 3D model of a home.

How to open a DDP file

You need a suitable software like Delphi to open a DDP file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your DDP file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a DDP file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert DDP files:

Delphi by Embarcadero
See the previous paragraphs to learn more about the main application. DDP files are often referred to as Delphi developers because this type of file is primarily created or used by this software.
7-zip (data) by Igor Pavlov
7-zip is a file compression software for Windows. It can decompress and unpack the contents of a ZIP-compressed DDP file. This file format is classified as Compressed.
DDAdd (protection parameters) by Microcosm
DDAdd is a program for configuring and protecting a Dinkey module. It uses a DDP file to store parameters for setting up a module. This file format is classified as Settings. Related links: Dinkey Pro/FD
Dsoft (data) by Inor
Dsoft is a program for configuring and calibrating DDP15 transmitters. It uses some data saved in a DDP file. This file format is classified as Data.
OS/2 (device driver profile) by IBM
OS/2 is a discontinued operating system for personal and business class computers. It uses a device driver profile saved in a DDP file. This file format is classified as System.

DDP file format:

To find out what program is needed to open DDP files, you need to determine the file format. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension or signature does not match the file format, errors will occur when opening or editing the file. When there is a problem with a file, the first step to solving it is to determine the file format. Below is our analysis of the DDP files:

DDP is seldom used as a file extension and includes different formats for different programs. But the following two file formats are common:

55% of all DDP files are DreamPlan Home Design Software Project files. They consist of illegible, cryptic characters. The files are 31 KB to 140 KB in size, with a median of 89 KB. This file type is based on cutting-edge technology. The following keywords are characteristic: lsdf and Ground Level. Examples of file names are Untitled.ddp. These files can be linked to home, design, house, plan, project and casa.
8% of all DDP files internally use the ZIP format, so multiple files are compressed and stored together in one DDP file. A DDP file includes 5 to 46 files. If you want to see the included files and images, simply rename the file extension to .zip and double-click it. The files are often between 9 KB and 250 KB in size.

All other DDP files (37%) have no consistent format, frequently e.g. Delphi Diagram Portfolio. Drag & drop your file here to see the file format and a preview of your DDP file!

a ddp diagram portfolio is a special file format by Embarcadero and should only be edited and saved with the appropriate software.

How to solve problems with DDP files

Associate the DDP file extension with the correct application.
Update your software that should actually open diagram portfolios. Because only the current version supports the latest DDP file format. Search, therefore, e.g. on the Embarcadero manufacturer website after an available Delphi update.
To make sure that your DDP file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
