Скопируйте все каталоги с файлами с FTP в локальный каталог

Я пытаюсь скопировать все каталоги, подкаталоги и файлы с FTP-сервера в локальный каталог. Часть файлов копируется успешно, но для остальных возникает ошибка 550 File not found, которые существуют на FTP и имена файлов с расширениями копируются в локальную директорию, но файлы повреждаются и не пригодный для использования. В чем причина повреждения остальных файлов при копировании?
