What are CBPROJ files and how to open them

Are you having problems opening a CBPROJ 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 CBPROJ files.

What is a CBPROJ file?

A .CBPROJ file is a Borland C++ Builder Project file.

A Borland C++ Builder project file describes everything needed to build a C++ application using Embarcadero (formerly Borland) C++ Builder, including what code files are included, which compiler and linker options are used, and how forms and resources are organized. It holds settings such as target platforms, debug/release configurations, paths, versioning, conditional compilation flags, and resource links.

Such a project file is created and maintained by the C++ Builder IDE. When new files (such as source modules, headers, form definitions) are added or removed, or when build settings (optimisations, include paths, libraries) are changed via the project options, the project file is automatically updated. During compilation, the developer's chosen options stored in this file guide the compiler, linker, and build tools in producing the executable or library.

Internal structure is XML-based and built on MSBuild-style project definitions. It uses tags like CppCompile, ItemGroup, PropertyGroup, BuildConfiguration, ProjectExtensions, ProjectType, and ProjectGuid. Signature indicators include an XML prolog and tags referencing "PROJECT XMLNS", "MSBUILD", "PROPERTYGROUP CONDITION", and "ITEMGROUP", along with keywords such as "BORLANDPROJECT", "PRODUCTVERSION", and "PROJECTGUID".
