# Themes

### General

Mail & Deploy supports themes that can be used to control how the user interface looks. Themes are stored in the *Data\Ui\Themes* directory of the root installation directory of [Mail & Deploy Server.](/release35/docs/server)

### Format

Every theme is an XML file that contains settings to control:

- The icon to display in the browser tab.
- The product name to display in the browser tab.
- Colors of many user interface items (such as buttons, input fields etc.).

          WARNING

          

There always must be a theme file named *Default.xml.* If that file does not exist, errors may occur and users might not be able to connect to the user interface.

Every [User](/release35/docs/users) can have a theme assigned that will be applied when that user connects to a user interface of Mail & Deploy.
