gistfile1.txt

function modify_post_mime_types( $post_mime_types ) {

	// select the mime type, here: 'application/pdf'
	// then we define an array with the label values

	$post_mime_types['application/pdf'] = array( __( 'PDFs' ), __( 'Manage PDFs' ), _n_noop( 'PDF <span class="count">(%s)</span>', 'PDFs <span class="count">(%s)</span>' ) );

	// then we return the $post_mime_types variable
	return $post_mime_types;

}

// Add Filter Hook
add_filter( 'post_mime_types', 'modify_post_mime_types' );


// Other file type that Wordpress supports
//	'pdf' => 'application/pdf',
//	'swf' => 'application/x-shockwave-flash',
//	'mov|qt' => 'video/quicktime',
//	'flv' => 'video/x-flv',
