The DPJ file is supported on 1 operating systems. Depending on your operating system, you may need different software to handle the DPJ files. Below is a summary of the number of programs that support and open the DPJ file on each system platform.
What is DPJ file?
The file with the extension DPJ is the Developer Files file type. The creator of this file is Embarcadero Technologies, Inc.. Developer Files consists of 1205 similar files. Borland Delphi Project is supported by 1 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. It is recommended to use Delphi to handle this file. This is a program created by Embarcadero Technologies, Inc..
How to open DPJ file?
The main problem with Borland Delphi Project is that the DPJ file is incorrectly associated with programs. This causes the file DPJ 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 DPJ 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
In this case, you should first verify that the Delphi application is installed on the computer. The easiest method is to use the system search engine by entering the program name Delphi in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open DPJ files.
Programs to open DPJ file
Remember to download programs supporting DPJ files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Delphi with DPJ files
If, despite the installed application, the DPJ file does not start in the Delphi application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Delphi application as the default for handling the DPJ file.
Step 3. Update Delphi to the latest version
The fault may also lie with the Delphi program, it is possible that Borland Delphi Project requires a newer version of the program. In this case, use the Embarcadero Technologies, Inc. website or update the program from the application.
Step 4. Check for the following problems with the DPJ 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 DPJ files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the DPJ file that we want to open. As a result of the scan, sometimes it is not possible to recover DPJ files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the DPJ file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair DPJ file corruption. You can restore the file from a backup or use Embarcadero Technologies, Inc. help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted DPJ files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. It is best to move DPJ to a different directory.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the DPJ file again. Some anti-virus or backup software may occupy the DPJ file for a certain period of time. If the problem persists, restart the machine.
