CBP File

What are CBP files and how to open them

Are you having problems opening a CBP 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 CBP files.

What is a CBP file?

A .CBP file is a Code::Blocks Project file.

Code::Blocks Project files with the extension .cbp are used by the Code::Blocks IDE to store all the information needed to manage and build a software development project. They do not include the actual source or header code, but instead record which files are part of the project, how to compile and link them, and settings such as compiler flags, include paths, debug/release configurations, output details, and project metadata. This format enables Code::Blocks to reconstruct the project layout whenever the file is opened.

These files are created and updated only by Code::Blocks, either when a new project is made or when project settings are modified (like adding files or changing build targets). Developers typically edit project contents from within the IDE. When building the project, Code::Blocks reads the .cbp file to determine what to compile, which toolchains to use, and how to link output files. Support for languages like C, C++, Fortran and (via plugins) D are built in, and different build targets (for example "Debug" and "Release") are specified within. Workspaces (.workspace files) allow grouping multiple .cbp projects for related work.

Technically, a .cbp file is an XML document that starts with the usual XML declaration and then uses a root element named CodeBlocks_project_file. It includes a version number via a FileVersion element (with major and minor attributes), and sections (such as Build and Units) listing units (source or header files), build targets, compiler/linker options, and other options. One of the signatures is the ASCII string
