Files recovered but won't open

I was dragging a file from my Desktop to the recycle bin when something went wrong and half of my files on my Desktop disappeared. Recuva found them all, though only about half of them were in "excellent" condition according to Recuva. So, I told Recuva to "recover" those files that were in "excellent" condition. The problem is, when I try to open those files, I get a message saying that says "We can't open this file" and that "something went wrong". Any ideas?

As an addendum to the above, it appears that files that are said to be "recovered" but can't be opened are PDF and PNG files in case that means anything...
