C + + projects

A project in c + + Builder consists of a set of files among them the following, with the extensions:

• . Cpp source file C + +. File is available for the project (Proyect1.cpp). One per unit (Unit1.cpp).
• . Dfm contains the description of the form and components that comprise it. Each form has its file description.
• . Dsk state and appearance of your desktop when you save the project.
• . H header files containing the declarations of the classes.
• . Bpr project makefile. Contains information about files and compiler directives that need to build the program.
• . Obj files generated by the compiler after treating the source files.
• . Res binary resource file.
• . Tds Archive of debugger symbols.

To examine the files that are part of our project was to access the Builder Project Manager located in the menu View -> Project Manager.
