• Auto-Open: The folder containing your merged file opens automatically after processing.
• UI Improvements: Added version badge and instructional prompts.

🚀 Features

• Batch Import: Add multiple PDF files via file browser or Drag & Drop.
• Manual Reordering: Use "Move Up" and "Move Down" buttons to ensure the perfect page sequence.
• Smart Parsing: Automatically handles file paths even if they contain spaces.
• Standalone Utility: Can be built into a single .exe file that runs without Python installed.

🛠️ Installation & Setup

Prerequisites

To run the source code, you need Python 3.x and the following libraries:

pip install pypdf tkinterdnd2 pyinstaller

Running the App

python PDFMerger_v2.py

📦 How to Build the Executable (.exe)

Important: Because this version uses tkinterdnd2 for drag-and-drop, the build command is different from standard Python scripts. You must use the --collect-all flag to include the necessary system hooks.

1. Open your terminal/command prompt.
2. Run the following command:

pyinstaller --noconsole --onefile --collect-all tkinterdnd2 PDFMerger_v2.py

3. Your standalone application will appear in the dist/ folder.

📖 User Guide

3. Organize: Select a file and use the ↑ or ↓ arrows to change the order.
4. Merge: Click MERGE NOW.
5. Finish: Choose a save location. The folder will open automatically once done.
