DPROJ File

What are DPROJ files and how to open them

Are you having problems opening a DPROJ file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your DPROJ files.

What is a DPROJ file?

A .DPROJ file is a Delphi Project file.

Delphi Project files with the .DPROJ extension are used by Embarcadero's Delphi IDE (Integrated Development Environment) to store project configuration data. They are created when you set up or modify a Delphi application from version 2007 onward and record settings needed to build the software, such as which source files are part of the project, compiler and linker options, version information, platform targets, and build configurations. These files do not contain your program's code logic directly - they reference separate source files, forms, and resources.

When you open a Delphi project in the IDE or compile it using MSBuild or the command-line tools, the .DPROJ file is read to understand how the project should be built (which compiler settings, which platforms, etc.). The IDE also updates the .DPROJ file automatically as you add or remove source files, change build configurations (like Debug vs Release), or set other project options via the Project Options dialogs.

Technically, a .DPROJ file is an XML document structured for MSBuild compatibility. It includes elements and attributes defining properties such as output directories, defined constants, references to other files, project GUID, configurations, and platform targets. It often begins with an optional UTF-8 BOM and contains tags like Project, PropertyGroup, ItemGroup, and various setting names.
