Конвертер "Bookster" позволяет загружать электронные книги в формате FB2 и простые текстовые файлы TXT в стандартную читалку iOS "Книги". Поскольку читалка "Книги" не понимает форматы FB2 и TXT, в ней нельзя открывать тексты в этом формате. Но можно поступить по-другому: открыть FB2 книгу или текстовый файл TXT в приложении "Bookster", и уже оттуда загрузить ваш текст в приложение "Книги". При этом приложение "Bookster" само создаст файл в формате ePub, который является родным для приложения "Книги". Интересный факт, но приложение "Книги" не понимает даже самые простые текстовые файлы. Bookster исправляет этот недочет и позволяет загружать также и обычные текстовые файлы с расширением TXT в приложение "Книги". Как пользоваться приложением "Bookster": 1) либо скачиваем FB2 книгу из Интернета, либо отправляем книгу в Bookster из приложения Файлы (или любого другого приложения, в котором она находится), либо копируем ее с помощью iTunes в документы "Bookster"; 2) книга попадает в приложение "Bookster" и появляется у него в списке файлов; 2) в приложении "Bookster" нажимаем на появившийся в списке файл - производится конвертация этого файла из FB2 в ePub; 3) при завершении конвертации у файла появляется меню, в котором выбираем вариант "Скопировать в Книги"; 5) ваша книга открывается в приложении "Книги". "Bookster" также понимает ZIP-архивы, поэтому в него за один раз можно загрузить целую библиотеку.
