4 - Multi-lingual user-interface
TreePad's default user-interface language is English. By default all TreePad's user-interface elements (menus, buttons, messages, dialogs, etc.) are displayed in English.
To change the language in which TreePad's user-interface elements are displayed, you can download and install a free 'TreePad language pack'.
