Is there a way to batch rename PDFs in a folder with content from the file? i.e. the title field

Hi, I have a load of documents in a folder. Most have names like 2334.pdf, 3645.pdf etc. Does anyone know of a way to automatically get the title from withing each file and rename the file with that title i.e. doc title.pdf

I found a product from a-odf.com that claims to do this, but I was hoping to use adobe's product.

Thanks in advance
