In the Delphi domain, DCU stands for Delphi Compiled Unit. A DCU is a persistent file used by the Delphi compiler.

A DCU file is an intermediate file format between the source code contained in a Delphi unit and the object files used during the linking of a program. It's automatically generated by the compiler.

As this file is persistent, it's one of the keys of the Delphi compiler speed. It avoids, during a simple compilation, to recompile all the units used by a project (including the packages). To force a full compilation, the user has rather, according to the Delphi IDE dialect, to build a project, which regenerates each DCU even if they have already been precompiled in a DCU.
