If you want to use Ray renaming folder "ray" in Dolphin into something different, please follow:

1) Open "inc/header.inc.php" file and find these strings:

require_once($dir['root'] . "ray/modules/global/inc/header.inc.php");
require_once($dir['root'] . "ray/modules/global/inc/content.inc.php");

replace "ray" in the path with the new name

2) Open "inc/design.inc.php" file, find the next fragment:

$_page_cont[0]['ray_invite_js'] see more = "
<script type=\"text/javascript\" language=\"javascript\">
var sRayUrl = '" . $site['url'] . $sRayHomeDir . "';
</script>
<script src=\"" . $site['url'] . "ray/modules/global/js/integration.js\" type=\"text/javascript\" language=\"javascript\"></script>";

replace "ray" in $site['url'] . "ray/modules/global/js/integration.js

3) Open "inc/admin_design.inc.php" file and find next strings:

<script src="../ray/modules/global/js/integration.js" type="text/javascript" language="javascript"></script>

Also you should open the next list of files where you will need to search through the word "ray" and replace it with your new name:

inc/sharing.inc.php
admin/browseVideo.php
admin/post_mod_audio.php
browseVideo.php
profile_edit.php
uploadShareVideo.php
viewVideo.php

Hope, this will help you.
