My passport : no space available

Thanks for your reply!

No, i can copy a few photos without getting this message. It seems to be a problem related to the ipad : i can copy many photos (about 500Mb) from my Asus pad (android) or my pc (windows) with no problems, this via a wireless connection or a usb connection. Strange! My aim is to make space on my ipad by copying stuff to the external disk
