Explorer is domain specific component. It can be constructed using contract-id: @lightcomp.com/tahiti/shell-files;1. It is visible in the list of domain as Component.ShellFiles.

Components display embedded Explorer in the one window. It is possible drag&drop files from the explorer to other Tahiti windows or to drop files to the Explorer. There is only one option called Component.ShellFiles.Directory. This option allow to specify default directory when Tahiti is started.

Embedded Explorer has one dialog-bar. This bar can be positioned some way as other bars.

Update component allows to check if there is new version of the application and start update process. Component internally use internally Invoker to do update. It means Invoker have to be first correctly installed and configured. There are two options in the Tahiti.xml which have to be set correctly.

At the first component have to be enabled - have to be listed in the option SharedComponents.XPCOM.Load.

<Item name="SharedComponents.XPCOM.Load" type="string" 
   default="
      @lightcomp.com/tahiti/update;1
   ">
  <Description value="Shared XPCOM components."/>
</Item>

The second option is called Component.Update.InvokerFile and is also placed in the Tahiti.xml. It contains name of configuration file for the Invoker. Tahiti is using this file same way as Invoker.exe. This file is typically called tahiti-update.xml.

Component also allows to start update process from the server. It can be done by sending Action Object (.taobj) to the Tahiti. Such object can start check if there is new version. Action object can also contain several options which can force Tahiti to use different XML file for the check. Description of the Action Object and attributes is part of the DEP2 Specification.
