What is ~DP file?

The file with the extension ~DP is the Archive Files file type. The author of this format is Embarcadero Technologies, Inc.. Archive Files consists of 619 similar files. Delphi DPR Project Backup is most often found on 1 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. The Delphi application is recommended to open the file. It was released by Embarcadero Technologies, Inc..

How to open ~DP file?

An often recurring problem with Delphi DPR Project Backup is that ~DP is not associated with the correct program file. This causes the file ~DP to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the ~DP 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 Delphi

The first step is to check if the computer has the Delphi program installed. The easiest method is to use the system search engine by entering the program name Delphi in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file ~DP with Delphi. Later in this article you will find a list of programs that can open ~DP files.

Programs to open ~DP file

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

Step 2. Create association of Delphi with ~DP files

However, it may happen that the application itself does not cause the ~DP file to open in the Delphi application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. 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 Delphi application as the default for handling the ~DP file.

Step 3. Update Delphi to the latest version

If, however, after binding Delphi with Delphi DPR Project Backup there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Embarcadero Technologies, Inc. website and install the latest version.

Step 4. Check for the following problems with the ~DP file

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

Very often, the file may be size 0 or incomplete. Usually this applies to ~DP files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our ~DP file. However, remember that not every infected ~DP file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the ~DP files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair ~DP file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Embarcadero Technologies, Inc.
When reading, a message appears that the file was encrypted or corrupted. The encrypted ~DP 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. The problem is only writing to the file, not reading it. If possible, you can try to move the ~DP file to another location.
This problem usually affects more complex files. In this case, the ~DP file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file ~DP to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
