Tried to recover and found an outlook zip file I had saved with all my old email info. It had been deleted. Recuva found it but when I tried to save it it says I have insufficient disc space. It indicates a huge KB amount but I know the file can't be that big. It was saved from a vista computer and I am saving it now to a win7 64bit. Anybody know why it is showing up so large?? Thanks
