<?
$files = array_diff(scandir('dirname'), array('.', '..'));
foreach ($files as $name) {
$file = file($name);
$newname = translit_name($file[0]);
rename('dirname/' . $name, 'dirname/' . $newname . '.txt');
}
$file = file($name); конечно памяти сожрет много, можно оптимизировать, но для разового действия сойдет
<?

Функция транслита думаю такая сойдет если что поправь ручками или поищи в инете получше
