What is the .DCU File Extension?

.DCU File Extension Description:

The file extension DCU is described as Delphi Compiled Unit. It is created when a .pas file is compiled by the Delphi application, which was developed by Borland Software Corporation.

The file with a DCU extension is in binary format and contains the codes and data used in the .pas file with the same filename. The file with the DCU extension provides an intermediate point between source codes in the PAS file and the compiled codes.

The file with the DCU extension contains all the source codes and data used by the PAS file. You will notice that the compilation to create a .dcu file of a .pas project is fast. This is because the instructions are already present and need not be recreated. The compiler only needs to create another file with a .dcu file extension and save the source codes there.

In case the .dcu file is deleted, you can recompile the PAS file to create a new file with a DCU format. Also, when changes have been made in the PAS file, the compiler will update the information inside the .dcu format by recompiling it.

In addition, since the DCU format is universally compatible with other programming languages, this allows the programmer to incorporate, or transfer, Delphi codes into other programs. This is made possible by cracking the DCU file against some third-party software.

The Delphi programming language is an object-oriented version of the old Pascal application, which was originally made for DOS-based programming. The latest release is version 7, which is being used to create desktop applications, as well as business oriented tasks.

Delphi is currently embedded with support into other programming languages, like C++, PHP, Pascal, and so on.
