Windows resource script
From Just Solve the File Format Problem
A Windows resource script (also called a resource file, and other similar names) is a text-based file used to define resources used in the development of Microsoft Windows software.
Although resource scripts can be written manually, a specialized resource editor is usually used instead.
A resource script is typically compiled to a Windows resource (.res) file or .o file, and then linked into an EXE or DLL file.
