move_uploaded_file failed to open stream: No such file or directory

When I send a photo to update the profile on the system, it returns the following fault: move_uploaded_file (/isequi/public/assets/img/user_pic/062701-20160807-suicida.jpg):  failed to open stream: No such file or directory in C: \ xampp \ htdocs \ isequi \ sys \ class \ user.php

The environment for testing is windows 7 with xampp.

Code used:

$this->picName = basename($_FILES['userPicture']['name']); 
        $this->picExtension = pathinfo($this->picName, PATHINFO_EXTENSION); 
        $this->picSize = round($_FILES['userPicture']['size'] / 1000); 

        if($this->picSize == 0) {
            $functions -> generateJsonMsg('selectPicture', null, null, null, $message->message['selectPicture']);
        }
        if($this->picSize > 100)    {
            $functions -> generateJsonMsg('fileIsTooLarge', null, null, null, $message->message['fileIsTooLarge']);
        }
        $functions -> isInArray($this->picExtension, $this->arrayPictureExtensionPermitted, 'extensionNotAllowed', $message->message['extensionNotAllowed']);   

        $this->picName = date('sih-Ymd').'-'.$this->picName;
        $this->picNameDirectory = '/webpage/public/assets/img/user_pic/'.$this->picName;

        if(move_uploaded_file($_FILES['userPicture']['tmp_name'], $this->picNameDirectory)) {
