How to browse all user directories w/ckfinder

Hello,
I'm using ckfinder with drupal. I've set up ckfinder to store uploaded images in 'sites/default/files/user%u/images/' where %u is the user ID.
When I browse the server with ckfinder, I only see the files uploaded to my directory, i.e. in .../files/myuserID/images.
Is it possible to set up ckfinder to browse all upload directories (as an admin only, of course)?
Thanks
