RSC File – What is .rsc file and how to open it?

RSC File: Overview

A Resource Script or RSC file is a plain text file that contains instructions and references to various resources used in a software application. Developed by Nokia, RSC files are primarily associated with the Symbian operating system, which was widely used on mobile devices. These files serve as a central repository for managing different types of resources, including images, icons, menus, dialog boxes, and other visual and functional elements of an application.

Structure and Contents of an RSC File

RSC files are organized into sections, each starting with a keyword followed by a colon. The main sections include:

• SOURCE: Lists the source files containing the actual resource definitions.
• TARGET: Specifies the name of the compiled resource file (.mbm) to be generated.
• RESOURCE: Defines individual resources, specifying their type, name, and other properties. These definitions can include references to external files or inline data.
• ALIAS: Creates aliases for resources, allowing them to be accessed using different names or identifiers.
• DESCRIPTION: Provides metadata about the RSC file, such as the author, version, and dependencies.

Opening RSC Files on Symbian Systems

Symbian Resource Script (RSC) files are binary files that contain compiled resources for Symbian Symbian OS applications. These resources include images, icons, sounds, and other data used by the application. To open an RSC file on a Symbian device, the user must have a file manager that supports the Symbian file system. Once the file is located, it can be opened using a resource editor, such as Carbide.c++ or Eclipse. These editors allow users to view and edit the contents of the RSC file, including the various resources it contains.

Opening RSC Files on Non-Symbian Systems

Opening RSC files on non-Symbian systems requires a specialized tool or emulator. One option is to use the Symbian Emulator SDK, which provides a virtual Symbian environment on a PC. Once the SDK is installed, the RSC file can be opened using the appropriate emulator. Alternatively, a third-party tool such as Symbian Resource Extractor can be used to extract the resources from the RSC file without the need for an emulator. These tools allow users to view and extract the contents of the RSC file, enabling them to access the resources it contains even on non-Symbian systems.

Symbian Resource File

RSC files are Symbian application compiled resource files. They contain compiled version of application resources, such as images, icons, and strings. RSC files are typically generated from source resource files using the Resource Compiler (RC) tool. The RC tool takes a source resource file, which is a text file containing definitions for the resources, and compiles it into a binary RSC file.

The RSC file is then included in the Symbian application package (SIS) file. When the application is installed on a Symbian device, the RSC file is extracted from the SIS file and stored on the device. The application can then access the resources in the RSC file at runtime.

RSC files are an important part of Symbian applications. They allow developers to package all of the application’s resources into a single file, which makes it easier to distribute and install the application. Additionally, RSC files can be compressed, which can reduce the size of the application package.
