Please, IS IT possible to orderby Filename decrescent?

I already bought two licenses of ckfinder and need to buy more, but I need to KNOW if it's possible to change the orderby filename to be descrescent insted o ascending, in ckfinder, or should I search for other solution? I don't need a to be at the settings pane, I can just change the code for Alway orderby Filename decrescent. I already posted this question and there was no answer. I would realy like to keep using ckfinder in the systems I build. Thank's.
