# Open UI files in Qt Design Studio

By default, Qt Creator opens QML files (`.qml`) and UI files (`.ui.qml`) in a visual editor called Qt Quick Designer in the Design mode.

To open `.ui.qml` files in Qt Design Studio instead:

1. Go to Preferences > Qt Quick > QML/JS Editing.

2. In Open .ui.qml files with, select Qt Design Studio.
