How to move group file widget to right sidebar

Hi. I am trying to move the enabled group file widget to the right sidebar on the group profile page. I can see that in groups/profile/layout.php file

// views/default/groups/profile/layout.php
....
echo elgg_view('groups/profile/widgets', $vars);

so I look into the groups/profile/widgets.php file

// enable tools to extend this area
echo elgg_view("groups/tool_latest", $vars);

but I couldn't find this groups/tool_latest view. So what is this tool_latest view and how can I achieve to move only the group file widget (not others) to the right sidebar? Thanks
