I don't even know how to phrase this question so I hope someone can help me. I've downloaded some pdf's on the kindle fire and initially they'll show up in the drop down list, but after I open them up via the tool bar they don't appear anywhere after that. I don't know how to find them. There not in documents, apps, books, anywhere. I've redownloaded the same pdf and the second time it had a little 1 next to the file name. So I know they're in there somewhere. Any help? Thanks.
