How to delete file uploaded by Plupload

I follow the steps from here to integrate the plupload in metabox. Everything is working fine. But I did find one disadvantage of this guide. When I click the 'Remove' link from the uploaded images, it only removed it from the post, not actually deleting it in the directory.

Another example of using plupload in metabox is RW Metabox plugin. This plugin does delete the file entirely when the "Delete" link is clicked. But I just can't figure it how he did in their code.

Can somebody here tell me how can I apply the 'Delete' feature in plupload with jquery?

To delete a file from the file system, you can use something like this attached to an AJAX hook that is called by jQuery:

function ajax_remove_image() {
    check_ajax_referer( 'image_removal', 'image_removal_nonce' );

    if ( ! $_POST[ 'confirm' ] )
        exit( 'false' );

    $uploads       = wp_upload_dir();
    $upload_dir    = $uploads[ 'path' ];
    $file          = strpos( $_POST[ 'file' ], '/' ) !== false ? $_POST[ 'file' ] : $upload_dir . '/' . $_POST[ 'file' ];
    $attachment_id = null;

    @unlink( $file );

    if ( ! file_exists( $file ) )
        exit( 'true' );
    else
        exit( 'false' );
}

This code comes from a plug-in that I am currently working on (source), so you may have to adjust it as necessary.
