Borland Project Group

The Borland Project Group format (extension .bpg) is a text-based project grouping file used in older versions of Delphi (up to Delphi 7 and earlier). It allows developers to group multiple individual projects together - such as applications, libraries, or modules - that work together as a single unit. The project group file helps organize related projects so that they can be opened, built, and managed together within the Delphi IDE's Project Manager.

Each .bpg file is created and maintained by Embarcadero Delphi (originally Borland). When you use the Delphi IDE to save a project group, it writes this file. It doesn't compile code itself - instead it records which sub-projects belong to the group, their order, file paths, project options, and dependencies. When you build or open the group in the IDE, Delphi reads the .bpg file to reconstruct the group structure so you can jump between projects and compile them as related pieces.

Inside the file, content resembles a makefile style syntax. It typically begins with a long ASCII line of hyphens ("#------------------------------------------------------------------------------") and includes keywords and macros such as VERSION, DEFAULT, and root or make directories (for example, variables like ROOT and MAKEDIR). It may reference project tools like MAKE.EXE, DCC32.EXE, or BRCC32.EXE. These strings appear in the byte signatures recorded for this format.
