After a weekend trying to fix the bl*#dy computer I have now got a problem with the Kindle app. on my Android tablet.
I was doing some housework on it - deleting files, loading new books etc when suddenly the Kindle directory disappeared with all my books

When I went into the Kindle app on my tablet the only books that were there were the Amazon books. I uninstalled & reinstalled the app hoping that this would fix it but no luck. I then just created a new folder called Kindle & copied a book to it but when going into Kindle on the tablet it wasn't there.
Can any of you guys help me or suggest where else I can copy books to? Not that this has ever worked before. The only place I have ever been able to read them from has been the Kindle folder.
Much appreciated
Larry
