Opening DPR Files

The DPR file type is primarily associated with Delphi.

DPR	File extension: DPR
	File type:	project

What is a DPR file?

DPR files mostly belong to Delphi by embarcadero. Files with DPR filename extension usually contain the source code of the main file in a project created with Delphi integrated development environment. This DPR file is the entry point into a Delphi project and it contains source code written in the Delphi dialect of Object Pascal programming language. The file also contains unit names used in the application, the paths to the scripts, form names, and instantiations of auto-create forms. Other FreePascal and Object Pascal compilers also use DPR as the filename extension of their main project files. C++, an integrated development environment for building C and C++ applications, uses DPR files to store its default projects. DPR filename extension is also associated with the vector graphics file format used by the discontinued Digital Interplot server-side data plotting software. This type of DPR files contain technical drawings such as maps an engineering diagrams.

How to open DPR files

You need a suitable software like Delphi to open a DPR 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 DPR file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a DPR file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert DPR files:

Delphi by embarcadero
See the previous paragraphs to learn more about the main application. DPR files are often referred to as Delphi developers because this type of file is primarily created or used by this software.
C++ Builder (default project) by embarcadero
C++ Builder is an integrated development environment for building cross-platform native applications using C++ programming language. DPR is the file format for saving default projects of some versions of C++ Builder. This file format is classified as Developer. Related links: Borland C++
Dance Paranoia
Dance Paranoia was a music and dance simulation game for classic computers. It used some data saved in DPR files. This file format is classified as Game.
Desk Project
WinTidy (data) by Ziff Davis
WinTidy was a Windows-based program used to backup and restore desktop layouts including icons, sorting order etc. Some data used by WinTidy are saved in DPR files. This file format is classified as Data.

DPR file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. The file format can be deduced from the file extension and the signature. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. So you need a detailed analysis of a file to find out the format and the associated program. Below is our analysis of the DPR files:

The DPR file extension is used very often and is used by a few programs, each with its own file format. But the following two file formats are common:

35% of all DPR files start with the bytes DP, which are crucial for this file format. If you open these files in a text editor, you can view and read the content yourself. Most of these files are 350 bytes to 9 KB in size. The file type is a fairly new file format. Files like these are about hcscil, covid, amerigroup, carefirst, simplyhc, aetna, athmbcbsco, anthemva, bcbstxg and bcca.
35% of all DPR files are Delphi Project source files. These files are text files, so they contain words and text. A typical file size is 430 bytes. Certain words are almost always found in the files, such as program, uses, Forms, begin, {$R *.res}, Application.Initialize; and APPTYPE CONSOLE. A usual file name is Project1.dpr. Such DPR files store data about igapack and demo.

All other DPR files (30%) have no consistent format, frequently e.g. DPR and MLS. They are often associated with advent or hard. Just click the "Choose your .dpr file to analyze" button on this page to find out what your DPR file is.

a dpr project is a special file format by embarcadero and should only be edited and saved with the appropriate software.

How to solve problems with DPR files

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