I'm trying to write a PHP script to copy the files from your local machine to a server:

$destination_directory = 'I:\path\to\file\\' . $theme_number;

if(!@opendir($desination_directory)) {
    echo 'Sorry, the destination directory could not be found.';
    die();  
}

I check the access to the destination folder with that process, and I keep getting the error return. Anyone know what I'm doing wrong? I pretty much have everything else in place. I just don't know how to access this other server.
