Files with the .RES extension contain Windows system resources – the win32 API in binary form. They are used during the compilation of C++ software source code.
RES files can contain data such as bitmap-images, cursors, and version information. Unlike win16 resources, win32 supports, inter alia, string coding in UNICODE.
