What is a DDP file?

A .DDP file is a data file that has a few possible formats. The most common format is a DreamPlan Home Design Project created by NCH Software. These files store house floor plans, 3D models, textures, and furniture layouts. Another common format is a construction project budget file used by PRESCOM software. PRESCOM uses a standard .ZIP archive renamed with the .DDP extension. Finally, software developers use .DDP files as Delphi Diagram Portfolio files within Embarcadero Delphi.

How to open DDP files?

To open a DreamPlan Home Design Project, you must install the DreamPlan Home Design software. If your .DDP file is a PRESCOM budget file, you can change the file extension to .ZIP and extract the contents using an archive tool like 7-Zip. If you have a Delphi diagram file, you need the Embarcadero Delphi development environment.

How viewer.online helps

Because a .DDP file has multiple possible meanings, you might not know which software to install. viewer.online/ddp can analyze .DDP files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.

Summary

viewer.online/ddp is useful for identifying, inspecting, and understanding .DDP files without installing software or dealing with compatibility problems.
