When Notepad++ starts, it looks into its Plugins configuration folder and loads whatever dll it finds. Later, you can add plugins using the <spanclass="menu_item">Settings -> Import -> Import plugins</span> menu.

<p>If a plugin misbehaves, Notepad++ will go out of its way to prevent the failure from propagating so as to avoid any loss of data. In such a case, you will be presented with information about the plugin reporting a problem. Making this information available on the Plugin Development forum will help removing the cause of the problem as soon as possible.
