/* ЗАМЕТКА РАЗРАБОТЧИКУ
*
* В данном файле размещаются подпрограммы для управления файлами, которые
* вызываются из MainWindow.cs. Также планируется использование этих подпрограмм
* после реализации текстовой коммандной строки FC (которая внизу окна).
* Все комманды работают с активной и пассивой панелью - Active/PassivePanel.
* FC всегда их определяет сам. Пассивая панель - всегда получатель файлов.
* Названия комманд - UNIX в верблюжьем регистре (Ls, Rm, MkDir, Touch и т.п.).
* Всем коммандам параметры передаются строкой, но допускаются исключения, напр.,
* если базовая функция "перегружена" функцией для нужд графического интерфейса.
* Sorry for my bad english.
