FileSystem Visualizer

A small Windows Forms (.NET 9) application that scans a folder, builds an in-memory file/folder tree using the Composite pattern, and renders visualizations (tree layout, bar chart) using a pluggable Strategy pattern.

Demo

Why this project is useful

• Quickly inspect folder structure and aggregate sizes without opening Explorer repeatedly.
• Visual comparison of folder sizes (bar chart) and hierarchical layout (tree) for quick analysis.
• Extensible architecture: add new visualization strategies or export features with minimal changes.

Features

• Recursive folder traversal with size calculation (Composite pattern).
• Multiple visualization strategies (Strategy pattern) — tree and bar chart included.
• TreeView summary and graphical panel rendering.
• Handles inaccessible folders gracefully (skips unauthorized folders).
