Change default upload directory (Coldfusion)

Hi, how can I change the default upload directory in CF? I modified fckeditor/editor/filemanager/connectors/cfm/config.cfm to the following:

   Config.UserFilesPath = "C:\Websites\qwert123\files\" ;

   Config.ServerPath = "C:\Websites\qwerty123\files\" ;

   Config.TempDirectory = "C:\Websites\qwerty123\files\" ;


   Config.FileTypesPath["File"]          = Config.UserFilesPath ;
   Config.FileTypesAbsolutePath["File"]    = iif( Config.ServerPath eq "", de(""), de(Config.ServerPath) ) ;
   Config.QuickUploadPath["File"]          = Config.FileTypesPath["File"] ;
   Config.QuickUploadAbsolutePath["File"]    = Config.FileTypesAbsolutePath["File"] ;

Yet when I run my test and upload a PDF file, nothing happens. I do not get any errors. Just the little animation bar runs...

Thanks!!
