use \Bitrix\Main\{ Application, IO };

$iterator = new \RecursiveIteratorIterator(
    new \RecursiveDirectoryIterator(Application::getDocumentRoot() . '/upload/MY_FOLDER/', \RecursiveDirectoryIterator::SKIP_DOTS | \FilesystemIterator::FOLLOW_SYMLINKS),
    \RecursiveIteratorIterator::SELF_FIRST
);

foreach($iterator as $item) {
    if ($item->isFile()) {
        $file = new IO\File($item->getPathname());

        echo \sprintf('<a download href="/%s">%s</a>', \str_replace(Application::getDocumentRoot(), '', $file->getPath()), $file->getName());
    }
}
