Platforms may show your application icon in different contexts, such as an application launcher or a settings window. The icon resolutions that you need depend on the target platform. When you deploy your application, you must provide your application icon in different resolutions. If you want all your new projects to use your own icons, replace these default icon files with your own files. The table below shows the paths where you can find the RAD Studio default icons, relative to the RAD Studio installation path: C:\Program Files (x86)\Embarcadero\Studio\22.0. The following sections explain how to configure your application to use your custom icons. However, before you publish your application you must replace the default RAD Studio icons with custom icons for your application. RAD Studio provides default application icons, so that you can test your application on any platform even if you do not have icons for your application yet. Some platforms do not allow running applications that do not provide application icons. 5.2 Cannot Define an App Icon for My Command-Line Application.
