Information about the .dcu (dcu) file type

Below is all the information we have available on file about the .dcu (dcu) file type.

Delphi Compiled Unit. A binary file which is generated by (Borland) Delphi when compiling a source file (.pas). Delphi will automatically recompile .dcu file if the source file has been updated or if the .dcu file is missing.

Where this is available we would like to include file format information on .dcu files, as well as information on how to view or open files of type .dcu. If you know of any information which we have missed then please let us know.
