To view the list of file types recognized by IntelliJ IDEA, in the Settings/Preferences dialog Ctrl+Alt+S, go to . If a file in your project is marked with the icon, it indicates that IntelliJ IDEA can't recognize it. In this case, you can register and configure a new file type.
Gutter icons are located in the editor on the left. Every icon in the gutter has a tooltip that explains its meaning and provides additional actions. For example, you can navigate to the related element, run a test or a method, and so on.
The list available gutter icons depends on the configuration of your project, the frameworks that you use, and the plugins that you have installed. To access the list of gutter icons available for your project, go to.
For more information on gutter icons, refer to Gutter Icons.
