Forgive me if this has been asked/answered elsewhere, but...
I have put files onto Pages and the Kindle app by emailing them to myself, then opening them up in the app. When I've finished with them, I deleted them - and they no longer appear when I open the app. But...when I look at the app in iTunes file sharing, the files are still there -- and I can even save the file onto the PC, so it's definitely still in the Pad somewhere. How do I find and delete them for good?
