How to get the just the filename of the uploaded file

I have a loop of file uploads and I want to get just the filename of file uploaded not the whole url where the filename is uploaded.

For example I uploaded a document file, I want to link to the file and the title of the link is the name of the file.

word_document_file.doc

I have this code and this outputs the whole url, not the name of the file.

<?php
	if ( CFS()->get('files') ):

	echo "<ul class='small-block-grid-1'>";
	$cfsloop = CFS()->get('files');
	foreach ( $cfsloop as $row ) {
		echo '<li><a href="';
		echo $row['upload']; // a sub-field named "gallery_title"
		echo '" class="button">';
		echo $row['upload'].'</a></li>';
	}
	echo "</ul>";

	endif;
?>
