# Recognized file types To view the list of file types recognized by CLion, go to `Settings | Editor | File Types`. If a file in your project is marked with the ![](https://resources.jetbrains.com/help/img/idea/2026.2/app.fileTypes.unknown.svg) icon, it means that CLion couldn't recognize it. In this case, you can [register](creating-and-registering-file-types.html) a new file type. | File Type | Icon | | --- | --- | | ActionScript files |
