changing path of ckfinder's load folders

Hi, I'm new with this application. I'm using the PHP version and I want to change the path of Images, Files, Flash and Multimedia to be uploaded and searched into a unique parent folder and get all files from the same folder.
I know that's carzy to modify EVERY FUNCTION that validate, and verify to get this result (witch I don't know all of them... ) . So i'm asking if there is a an easier way to do that, I'm forced (due to client's requirement ) to modify that in order not to migrate every user's files on the existent server creating Images, Files, Flash and Media sub-folder for every user, clasify and move every file into it's respective folder.

Please I need some help with that and resolve this problem or also give me any alternative solution to this

Thanks
