Borland C++ Builder was a Windows development environment for creating applications in the C++ programming language. A BCB file belongs to the development data used by that software.
The file can contain information required by a C++ Builder project or another part of the development environment. Its contents are intended for use by C++ Builder.
The BCB format is software-specific and is not a general-purpose data interchange format. It is mainly encountered with older Borland C++ Builder projects and files.
Open the file on Microsoft Windows with Borland C++ Builder, the development environment associated with the format. As far as is known, this file type is usable only with Borland C++ Builder. Open it from within the relevant C++ Builder project when possible.
A text editor or general-purpose viewer is unlikely to display the file correctly. If an installed version of C++ Builder does not recognize it, the file may have been created by a different version or may require its associated project files.
There is no known general-purpose converter for the .bcb file format. It is tied to Borland C++ Builder and is not normally converted independently.
To move a project to another development environment, open it in a compatible version of C++ Builder and migrate or recreate the project there, exporting the source and other usable project files separately.
