ftp - Error with Opencart Exstension Installer -

i new opencart , not technically experienced. have searched reply everywhere know. have installed opencart2 on local machine , want utilize exstension installer. scheme uses ftp, created local ftp using filezilla server. no problems. set opencart scheme ftp setting ftp credentials. ftp root set localhost/mydomain on running extension installer next error: "syntaxerror: json.parse: unexpected character @ line 1 column 1 of json info ok <warning: ftp_chdir(): cwd failed. "/:/localhost/mydomain": directory not found. in c:\xampp\htdocs\mydomain\admin\controller\extension\installer.php on line 228{"error":"could not set root directory "}"]

i have tried various combinations of ftp root folder i.e. localhost, , nil seems rid of error. grateful if guide me.
