+<p>If the custom preferences file is used as described above, setting the <tt>org.eclipse.ui/default_dialog_settings_rootUrl</tt>
+property in that file allows to specify a folder containing default dialog settings values for product plug-ins.
+The property value must be a valid URL.<br>
+The preference can be set using the following URL schemes.
+</p>
+<pre>
+org.eclipse.ui/default_dialog_settings_rootUrl=http://mycompany/dialog_settings
+org.eclipse.ui/default_dialog_settings_rootUrl=file:/etc/mycompany/dialog_settings
+org.eclipse.ui/default_dialog_settings_rootUrl=platform:/plugin/my.company.bundle/dialog_settings
+</pre>
+<p>
+The directory specified by this URL must contain folders with
+<tt>dialog_settings.xml</tt> files for every plug-in to be customized,
+each directory with the symbolic name of concrete plug-in,
+such as such as <tt>dialog_settings/org.eclipse.ui.ide/dialog_settings.xml</tt>, <tt>dialog_settings/org.eclipse.ui.navigator/dialog_sttings.xml</tt>, <tt>dialog_settings/my.company.bundle/dialog_settings.xml</tt>...
+Those <tt>dialog_settings.xml</tt> files for each bundle can be retrieved from a running instance of the Eclipse Platform, under the folder <tt>${workspace}/.metadata/.plugins</tt>. You can simply copy-paste those existing files into the directory set as value for the <tt>org.eclipse.ui/default_dialog_settings_rootUrl</tt> preference.
