+## Файловый менеджер на .NET MAUI
 
-MAUI Commander
\ No newline at end of file
+**Разработчик:** Пилипенко Степан Андреевич (2025 год)
+
+---
+
+## Введение
+
+### Цель работы
+Разработка кроссплатформенного файлового менеджера с использованием современной технологии .NET MAUI, обеспечивающего эффективную работу с файловой системой на различных операционных системах.
+
+### Актуальность
+В современном мире с ростом мобильных устройств и разнообразием операционных систем возрастает потребность в кроссплатформенных решениях. Файловые менеджеры остаются одним из наиболее востребованных типов приложений, а возможность их работы на разных платформах из единой кодовой базы значительно сокращает затраты на разработку и поддержку.
+
+## Выбор технологий
+
+### .NET MAUI как основная платформа
+**Обоснование выбора:**
+
+1. **Единая кодовая база** - возможность разработки для Windows, macOS, Android и iOS из одного проекта
+2. **Производительность** - нативная компиляция и прямой доступ к API платформ
+3. **Современный UI** - поддержка последних стандартов пользовательского интерфейса
+4. **Экосистема .NET** - богатая библиотека компонентов и инструментов
+5. **Поддержка Microsoft** - долгосрочная поддержка и активное развитие платформы
+
+### Преимущества перед альтернативами
+- **По сравнению с Electron**: меньший расход памяти, лучшая производительность
+- **По сравнению с Flutter**: интеграция с экосистемой .NET, знакомый язык C#
+- **По сравнению с нативной разработкой**: сокращение времени разработки в 2-3 раза
+
+## Архитектура решения
+
+### Многослойная архитектура
+
+```
+┌─────────────────────────────────────────┐
+│             Presentation Layer          │
+│              (MainPage.xaml)            │
+└─────────────────────────────────────────┘
+┌─────────────────────────────────────────┐
+│              Business Logic             │
+│          (Сервисы, Менеджеры)           │
+└─────────────────────────────────────────┘
+┌─────────────────────────────────────────┐
+│              Data Access                │
+│        (FileSystemService, etc.)        │
+└─────────────────────────────────────────┘
+```
+
+### Ключевые компоненты
+
+#### 1. **Presentation Layer**
+- **MainPage.xaml** - основной пользовательский интерфейс
+- Две панели для навигации по файловой системе
+- Панель инструментов с основными операциями
+
+#### 2. **Business Logic Layer**
+
+##### PanelManager
+- Управление состоянием панелей
+- Навигация и выделение элементов
+- Координация между левой и правой панелями
+
+##### FileOperations
+- Копирование файлов и директорий
+- Перемещение элементов
+- Удаление и создание папок
+- Открытие файлов
+
+##### KeyboardService
+- Обработка клавиатурных сокращений
+- Кроссплатформенная поддержка горячих клавиш
+- Навигация с помощью WASD
+
+#### 3. **Data Access Layer**
+
+##### FileSystemService
+- Абстракция над файловой системой
+- Получение содержимого директорий
+- Кроссплатформенные пути
+
+##### PathHelper
+- Работа с путями файловой системы
+- Определение домашней директории
+- Кроссплатформенные операции с путями
+
+### Принципы проектирования
+
+#### 1. **Инверсия зависимостей (DIP)**
+```csharp
+public interface IPanelManager
+public interface IFileOperations
+public interface IKeyboardService
+```
+
+#### 2. **Принцип единственной ответственности (SRP)**
+Каждый сервис отвечает за конкретную функциональность
+
+#### 3. **Интерфейс-ориентированное программирование**
+Легкая замена реализаций и тестирование
+
+## Функциональные возможности
+
+### Основные операции
+1. **Навигация** - просмотр файловой системы через две панели
+2. **Копирование** (F5) - копирование файлов и папок между панелями
+3. **Перемещение** (F6) - перемещение элементов между панелями
+4. **Создание папок** (F7) - создание новых директорий
+5. **Удаление** (F8) - удаление файлов и папок
+6. **Быстрая навигация** - переход в домашнюю директорию
+
+### Управление с клавиатуры
+- **WASD** - навигация по файлам
+- **Space/Enter** - открытие файлов и папок
+- **F5-F8** - операции с файлами
+- **H** - переход в домашнюю директорию
+
+### Кроссплатформенность
+- Поддержка Windows и macOS
+- Единый код для разных платформ
+- Адаптация к особенностям файловых систем
+
+## Технические особенности
+
+### Обработка файловых операций
+```csharp
+public async Task<bool> CopyAsync(string sourcePath, string targetPath)
+public async Task<bool> MoveAsync(string sourcePath, string targetPath)
+public async Task<bool> DeleteAsync(string path)
+```
+
+### Навигационная система
+- Рекурсивный обход директорий
+- Поддержка специальных элементов (".." для навигации вверх)
+- Оптимизированная работа с большими директориями
+
+### Пользовательский интерфейс
+- Интуитивная двухпанельная layout
+- Визуальное выделение активных элементов
+- Статус-бар с текущими путями
+
+## Результаты разработки
+
+### Достигнутые цели
+1. ✅ Создан полнофункциональный файловый менеджер
+2. ✅ Обеспечена кроссплатформенность (Windows/macOS)
+3. ✅ Реализованы все основные файловые операции
+4. ✅ Обеспечена высокая производительность
+5. ✅ Создан удобный пользовательский интерфейс
+
+### Производительность
+- Быстрая загрузка директорий
+- Эффективная работа с большими файлами
+- Минимальное потребление памяти
+
+### Качество кода
+- Чистая архитектура с разделением ответственности
+- Полная покрытие интерфейсами для тестирования
+- Современные практики C# и .NET
+
+## Заключение
+
+Разработанный файловый менеджер демонстрирует эффективность использования .NET MAUI для создания кроссплатформенных приложений. Приложение успешно решает поставленные задачи и предоставляет пользователю удобный инструмент для работы с файловой системой на разных платформах.
+
+### Перспективы развития
+1. Добавление поддержки сетевых протоколов (FTP, SFTP)
+2. Реализация поиска по файловой системе
+3. Добавление предпросмотра файлов
+4. Поддержка плагинов и расширений
+5. Интеграция с облачными хранилищами
+
+### Выводы
+Использование .NET MAUI позволило создать производительное кроссплатформенное приложение с минимальными затратами на разработку. Архитектура на основе сервисов и интерфейсов обеспечивает легкую расширяемость и поддерживаемость кода, что делает решение перспективным для дальнейшего развития.
