Uploadify - change destination folder to another folder on different hardive

I am new to uploadify. I recently installed on a xamp in my local c:/ where uploadify resides. I have an uploads folder in the httdocs of xampp where all my uploads go. However I would like to move my uploads to a folder on a different drive. I've tried to edit the uploadifive.php but to no avail. I would like to move from '/uploads'(C:\xampp\htdocs\uploadify) to uploads in (L:\ibi\apps\ibisamp\uploads). I am using the html-5 version.

Here is my code:

index.php

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Elavon MDM</title>
<link rel="icon" type="image/ico" href="favicon.ico">

<script src="jquery.uploadifive.min.js" type="text/javascript"></script>
<link rel="stylesheet" type="text/css" href="uploadifive.css">
<style type="text/css">
body {
	font: 13px Arial, Helvetica, Sans-serif;
}
.uploadifive-button {
	float: left;
	margin-right: 10px;
}
#queue {
	border: 1px solid #E5E5E5;
	height: 177px;
	overflow: auto;
	margin-bottom: 10px;
	padding: 0 3px 3px;
	width: 300px;
}
</style>
</head>

<body>
<!--	<h1>Data Management Upload Demo</h1> -->
	<form>
		<div id="queue"></div>
		<input id="file_upload" name="file_upload" type="file" multiple="false">
		<a style="position: relative; top: 8px;" href="javascript:$('#file_upload').uploadifive('upload')">Upload Files</a>
	</form>

	<script type="text/javascript">
		<?php $timestamp = time();?>
		$(function() {
			$('#file_upload').uploadifive({
				'auto'             : false,
				'checkScript'      : 'check-exists.php',
				// 'fileTypeExts'     : '*.csv',
				'formData'         : {
									   'timestamp' : '<?php echo $timestamp;?>',
									   'token'     : '<?php echo md5('unique_salt' . $timestamp);?>'
				                     },
				'queueID'          : 'queue',
				'uploadScript'     : 'uploadifive.php',
				'onUploadComplete' : function(file, data) { console.log(data); }
			});
		});
	</script>
</body>
</html>

uploadifive.php

<?php
/*

*/

// Set the upload directory
$uploadDir = '/uploads/';

// Set the allowed file extensions
$fileTypes = array('jpg', 'jpeg', 'gif', 'csv', 'png'); // Allowed file extensions

$verifyToken = md5('unique_salt' . $_POST['timestamp']);

if (!empty($_FILES) && $_POST['token'] == $verifyToken) {
	$tempFile   = $_FILES['Filedata']['tmp_name'];
	$uploadDir  = $_SERVER['DOCUMENT_ROOT'] . $uploadDir;
	$targetFile = $uploadDir . $_FILES['Filedata']['name'];

	// Validate the filetype
	$fileParts = pathinfo($_FILES['Filedata']['name']);
	if (in_array(strtolower($fileParts['extension']), $fileTypes)) {

		// Save the file
		move_uploaded_file($tempFile, $targetFile);
		echo 1;

	} else {

		// The file type wasn't allowed
		echo 'Invalid file type.';

	}
}
?>

checkexists.php

<?php
/*

*/

// Define a destination
$targetFolder = '/uploads'; // Relative to the root and should match the upload folder in the uploader script

if (file_exists($_SERVER['DOCUMENT_ROOT'] . $targetFolder . '/' . $_POST['filename'])) {
	echo 1;
} else {
	echo 0;
}
?>

Solution

Try to replace

$uploadDir  = $_SERVER['DOCUMENT_ROOT'] . $uploadDir;

with

$uploadDir  = "L:\ibi\apps\ibisamp\" . $uploadDir;
