.bat reacts to files in a specified folder, how to make it react to files dragged onto it?

I downloaded a batch ringtone converter which allows me to batch convert files in the program's folder\mp3 folder. I like the .bat but I want to modify it so that it doesn't react to files in the \mp3 folder, but in files that are dragged onto the .bat file. And I want that I can drag MULTIPLE files onto it.

Is this possible in anyway? Thanks A LOT in advance. I suppose it's a simple code edit in the .bat below but I am not really an experienced user of Windows .bat files.

Here is the .bat file's code:

@echo off
echo **************************************************************
echo *  Convert mp3 into m4r                                      *
echo *                                                            *
echo *                                       by gary cheung       *
echo *                                                            *
echo *       This script only convert mp3 into m4r and you should *
echo *             unload the m4r using itunes or other methods   *

And if you need the whole package, I've uploaded it here.

If you drag-drop a file to a batch-script (.BAT file), the batch-file will be run with the drag-drop item as the first parameter.

So all you need to do is process the first parameter, which is indicated by %1.

For starters, in your .BAT file, add the line near the top:

echo The Drag-Drop file is %1

Then test that to make sure you can drag-drop to your batch file.

I am not sure if/how batch-scripts handle multiple drag-drop, but check the subsequent parameters (%2, %3, %4...) to see if that works for multi-file drag-drop.
