Описание формата файла

Compiled resource file used by applications of Symbian OS, an open source operating system designed for touchscreen devices, mobile devices, and smartphones; contains resources that are compiled from .RSS files into a binary format.

RSC files comprise a finished Symbian application together with an .APP file. They allow application developers to change the program resources without having to recompile the APP file again. This can be useful when localizing the application to different languages.

Nokia Web Runtime plug-ins, which allow users to compile RSC files, are available for Aptana Studio, Adobe Dreamweaver, and Microsoft Visual Studio.
