Setup

1. Prepare Your Environment
   Close all unnecessary windows to avoid interference with the automation process.

2. Place and Run the Script
   Place the script file in the folder containing the .pdn files you want to convert.
   The script will process all .pdn files in the folder and subfolders.

3. Recreate ORA Files Option
   When running the script, it will prompt you whether to recreate .ora files, even if they already exist.
   Select "Yes" to overwrite or "No" to skip existing .ora files.

4. Delete PDN Files Option
   You will also be prompted to choose whether to delete the .pdn files. Select "Yes" to delete or "No" to keep .pdn files.

5. Conversion Process
   The script will:

   • Open each .pdn file in Paint.NET
   • Save it as .ora using Paint.NET's Save As functionality
   • Close Paint.NET after each conversion
   • Move on to the next file

6. Command Line Usage
   You can also run the script from the command line:

   cd "C:\CONVERSION\PATH"
   python "C:\PATH\TO\convert_pdn_to_ora.py"
   

   Or with a specific folder path:

   python "C:\PATH\TO\convert_pdn_to_ora.py" "C:\CONVERSION\PATH"
   

   Replace "C:\CONVERSION\PATH" and "C:\PATH\TO\convert_pdn_to_ora.py" with the actual paths on your system.

Linux Compatibility

If you want to run this script on Linux,
you will need to use a Windows 11 virtual machine or a Windows installation,
as Paint.NET does not work under Wine.
The .pdn format has not been reverse-engineered for native Linux support.
