PDF files FROM iPad?

Hi, 

I would like to know if I can use the iXpand to transfer PDF files created in iWorks FROM my iPad to a PC. 

Thanks in advance. 

I was not able to find away to save it directly from Pages to the iXpand but I was able to text the pdf to myself from pages and then from the text message I was able to open the PDF in the iXpand app and save the PDF to the iXpand and then transfer it to my computer. A little convoluted but you can make it work. 

Hi, I have some questions I hope you can tell me :

  1. Can I use to store .pptx presentations or keynote?

  2. Is it truth that the maxium for a file must be 4 gb? 

Thanks in advance.
