Multiple artboards to multiple PDF's

I have over 300 different ai files with about 50 artboards in each one and need to export each artboard to a separate PDF file.  I'm on a windows machine so the script would have to be JavaScript.  Is this possible?

I found the following script on the forums, which is close, but I really need actual PDF files (not just "PDF compatible" ai files):

Thanks so much!

//splits the activeDocument Artboards into individual files

var doc = app.activeDocument;

var docName = doc.name;
var docPath = doc.path;
var fullName = docPath + "/" + docName;
var abRange = ""

for (i=1; i<=doc.artboards.length;i++)
    {
        abRange = abRange + i + ","
     }
IllustratorSaveOptions.saveMultipleArtboards = true;
IllustratorSaveOptions.artboardRange = abRange;

var newFile = new File(fullName);
app.activeDocument.saveAs (newFile, IllustratorSaveOptions);

alert ("Artboards Saved to current document's Folder", "Split Arboards");
