A modern graphical user interface (GUI) application for recursively parsing directories, selecting text-based files, and combining their contents into a single file.

• Modern UI: A clean, Apple-inspired interface built with Python's tkinter library.
• Comprehensive File Support: Intelligently detects a wide range of text-based files, including source code, configuration files, markup, and documentation.
• Interactive Directory Tree: Visualize and navigate the directory structure with an interactive tree view.
• Selective Parsing: Choose specific files and folders to include in the final output.
• Real-time Content Preview: See the combined content of selected files in real-time.
• Copy & Download: Easily copy the combined content to the clipboard or download it as a .txt or .md file.
• Detailed Status Bar: Get live updates on the number of files found, selected, and the total size of the combined content.

1. Ensure you have Python 3 installed on your system.
2. Save the code as a Python file (e.g., dirParser4.py).
3. Run the script from your terminal:

   python dirParser4.py

This application uses only Python's built-in standard libraries (tkinter, os, pathlib, threading). No external packages are required. An empty requirements.txt file is included to reflect this.
