## Overview

This is a Windows Forms utility for hiding arbitrary file contents in an image and extracting them later. The workflow is: select a carrier image and file, check capacity, embed file data and its name in image color-channel bits, save the resulting image; for extraction, load that image, recover the name and bytes, and save the file. The sampled implementation places UI handling and steganography logic together in Form.cs; the designer excerpt confirms separate encode/decode controls. Other event wiring is not fully shown.
