The following image illustrates the folder structure that the HelloWorldBasic example uses.
The HelloWorldBasic example contains the following folders:
data, which contains the resource files that are used for the UI and localization
doc, which contains documentation on the example. To open the documentation, open the folder and double-click the index.html file.
gfx, which contains the graphics used by the example
group, which contains the Build Configuration Files used to build the example for the emulator and the mobile device.
inc, which contains the application header files
sis, which contains the files required to install the application on a device. See Installation File.
src, which contains the C++ source code files
The files in the data, gfx, inc and src directories are the Source Files that are used to build the application executable and related resources.
This application structure is typical of Symbian application projects.
