How to change the resource browser root path?

I would like to have the MCPUK browser to sort a path which i say to do so but am driven crazy to find a solution.

Suppouse my resource is an image or flash, (under the FCKeditor resource browser) I have made sub-folders for the sake of fast image finding, Now i would like to have the resource browser to point to one of those sub-folders.

Is it clear what i am about to do?

Thanks for any comments!

This is what the rb_base_path and rb_base_url settings are for. Or am I misunderstanding what you want to do?

Based on setting names, Sounds those might do the trick but where exactly they are?
