Within the config.php file in the root of CKFinder you indicate a location with the chain of folders to be loaded in the "Backends" block:
$config['backends'][] = array(
'name' => 'default',
'adapter' => 'local',
'baseUrl' => '../../../../home/SEU DIRETÓRIO/',
'root' => '', // Can be used to explicitly set the CKFinder user files directory.
'chmodFiles' => 0777,
'chmodFolders' => 0755,
'filesystemEncoding' => 'UTF-8',
);
And in the block just below, you indicate the root folders of this note in the "Resource Types" block:
$config['resourceTypes'][] = array(
'name' => 'Caixa',
'directory' => 'CAIXA',
'maxSize' => 0,
'allowedExtensions' => '7z,aiff,asf,avi,bmp,csv,doc,docx,fla,flv,gif,gz,gzip,jpeg,jpg,mid,mov,mp3,mp4,mpc,mpeg,mpg,ods,odt,pdf,png,ppt,pptx,pxd,qt,ram,rar,rm,rmi,rmvb,rtf,sdc,sitd,swf,sxc,sxw,tar,tgz,tif,tiff,txt,vsd,wav,wma,wmv,xls,xlsx,zip',

);
