Filtering displayed results in CKFinder

Hi,

Is it possible to filter the contents of a folder displayed by CKFinder?

For example:
I have a folder of images which also includes some php files and some dat files. I want to be able to use CKFinder to just display the jpgs and to be able to specify which file extensions not to display, like you can do with 'denied extensions' and 'allowed extension'.

Any help will be appreciated!
