File types

To view the list of file types recognized by IntelliJ IDEA, go to Settings/Preferences (Ctrl+Alt+S) | Editor | File Types. If a file in your project is marked with the unknown file type icon, it indicates that IntelliJ IDEA can't recognize it. In this case, you can register and configure a new file type.
