Finding names/location of objects in a keynote presentation

I have to re do a keynote presentation in power point -- the export feature didn't work; I got the error message saying that PPT was unable to display some of the images and texts because they had become corrupted and it was not possible to recover the information.

Anyhoo... I was wondering: is it possible to find out the names and location of the objects and texts used in the presentation? That way I could simly copy them to a folder and use them on the pc and PPT. I know they have to be in the Mac somewhere.

Please help if you can
