What is DCU file?
The file with the extension DCU is the Developer Files file type. It was designed by Embarcadero Technologies. Additionally, the Developer Files category contains 1205 of other files. Delphi Compiled Unit is most often found on 1 operating systems. The file will work on Windows systems, unfortunately not on others. The Delphi application is recommended to open the file. It was released by Embarcadero Technologies, Inc..
How to open DCU file?
The main problem with Delphi Compiled Unit is that the DCU file is incorrectly associated with programs. Thus, when you open DCU, the program selection wizard or some other program starts. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the DCU 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. To do this, enter the name Delphi into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open DCU files.
Programs to open DCU file
Remember to download programs supporting DCU files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Delphi with DCU files
However, it may happen that the application itself does not cause the DCU file to open in the Delphi application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the DCU file with the Delphi program.
Step 3. Update Delphi to the latest version
If, however, after binding Delphi with Delphi Compiled Unit there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Embarcadero Technologies, Inc. page and install.
Step 4. Check for the following problems with the DCU file
The problem may also be with the file itself if the above steps don't work. The most common file problems are:
Very often, the file may be size 0 or incomplete. Usually this applies to DCU files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our DCU file. Sometimes virus-infected DCU files cannot be recovered, so make a backup in advance.
Older version of DCU file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular DCU file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Embarcadero Technologies
The program can also signal the fact of encryption. The encrypted DCU 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 of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move DCU 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 you have to wait for the session to the file DCU to close. Some anti-virus or backup software may occupy the DCU file for a certain period of time. If the problem persists, restart the machine.
