It's recommended to include error handling around file deletion to gracefully handle cases where the file might not exist or cannot be deleted.

Suggested change

	File.Delete(outputFilePath);
	if (File.Exists(outputFilePath))
	{
	try
	{
	File.Delete(outputFilePath);
	}
	catch (Exception ex)
	{
	Console.WriteLine($"Failed to delete the file: {ex.Message}");
	}
	}

Consider adding error handling or additional configuration options when starting a process to ensure robustness, especially in environments with strict security policies.

Suggested change

	Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true });
	if (File.Exists(outputFilePath))
	{
	try
	{
	Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true });
	}
	catch (Exception ex)
	{
	Console.WriteLine($"An error occurred while trying to open the file: {ex.Message}");
	}
	}
	else
	{
	Console.WriteLine("The file does not exist: " + outputFilePath);
	}
