📂 Custom Virtual File Explorer

A modern, high-performance Virtual File System (VFS) simulation and management application built using C# and Windows Forms (.NET 6.0). This project demonstrates core operating system concepts such as storage partitioning, dynamic space allocation, and hierarchical data structures through a polished user interface.

🚀 Key Features

• 💾 Virtual Storage Management: Initialize custom virtual filesystems with specified storage capacities (saved with a custom .dsfs extension).
• 🎛️ Dynamic Partitioning: Create and format custom partitions within the virtual drive. Ensures physical boundaries are respected with dynamic space constraint checking.
• 📁 Hierarchical File Management: Full support for directory trees. Create folders and import real files into the virtual environment.
• ✂️ Clipboard Operations: Integrated Copy, Cut, and Paste mechanics across different partitions or nested directories with automatic allocation size verification.
• 📊 Live Resource Tracking: Status bar indicators instantly update to show selected item types, raw storage size, and remaining free space.
• 🔒 Binary Persistence: Automatically flushes state and serializes the complete file tree architecture natively into a binary stream upon closure.

🛠️ Architecture & Design Patterns

The project deeply leverages solid Object-Oriented Programming (OOP) architectures:

1. Composite Design Pattern:
   • Node: Abstract base class representing any entity within the system.
   • Filesystem, Partition, Folder, MyFile: Inherit from Node to handle unified leaf/composite behavior.
2. Resource Allocation & Verification:
   • Dynamic sizing computation logic where the parent node monitors combined nested sizes while respecting maximum partition boundaries during file mutations.
