====== Extension Manager ======

The //extension manager// is where you load, remove, enable or disable [[bundywiki>plugins|L3DT plugins]], and is opened via the //'Extensions->Extension manager...'// menu option. It looks a little something like this:

{{ :l3dt:userguide:dialogs:extmanager.png |The extension manager}}





===== Load =====

The //Load// button is used to add new plugins. Plugins may be either '.zeo' or '.dll' files (case insensitive), but in either case they must be 32-bit Windows dynamic linked libraries that were compiled using the Zeolite plugin API ([[zeolite:downloads|available here]]).  It is recommended that plugins be placed in the '[L3DT path]\Extensions' folder.

===== Disable/Enable =====

You can enable or disable plugins using the dual-mode //enable/disable// button. If the plugin is a [[bundywiki>plugins:fileio|file input/output]] plugin, then any formats handled by this plugin cannot be used when it is disabled. 

<note important>
If a plugin crashes when loaded, it will be disabled when L3DT is next started. You can re-enable it here, using the //enable// button.
</note>

===== Remove =====

The //remove// button will, as the name suggests, remove the plugin from L3DT, and also removes any file formats handled by this plugin from the [[l3dt:userguide:io:preferences|file preferences]] dialog box (and elsewhere.)







===== Up / Dn =====

The plugins are loaded in the order they appear in the list. You can change the load order by moving the plugins up and down using the //Up// and //Dn// buttons. This allows you to change the load order of plugins.



===== OK =====

If you have made any changes in the manager, you will be prompted with the following dialog when you click OK:

{{ :l3dt:userguide:extensions:manager:ext_ok_msg.png |You must restart L3DT after messing with extensions, or VERY BAD THINGS might happen.}}

L3DT only initialises plugins when the application is loaded, and only removes them when it is closed, so re-starting is the only way to ensure that any plugins that you have removed are indeed removed, and any plugins you loaded are likewise loaded.
