Kindle files transferred to the iPad don't show up in the Kindle App

Hi,

OK, so I purchased a book through a kickstarter project. The author provided a DRM-free copy of the book in a couple of reader formats including .azw and .mobi.

I have both a Kindle and an iPad. I used the Kindle's USB connector to copy the .azw file over to the Kindle. I disconnected the Kindle, started it up, and the book is there no problem I can start reading.

So now I want to transfer the book to my iPad so I can read it through the Kindle app.

I connect the iPad to my MacBook and open up iTunes.

In iTunes, I see that the iPad is connected and I open it up.

I go to Apps and scoll down to File Sharing.

I select Kindle and add the .azw file to the list of files shared to that app.

I hit sync.

When I disconnect and open up the Kindle app, I don't see the book I've transferred over.

I try the .mobi version and it doesn't show up either.

I have done this with other books so I'm a bit surprised this one didn't transfer.

So my questions:

1.) Any other tricks for getting the Kindle app to see the book I've transferred to the ipad.

2.) If the Kindle app can't read the book, is there a way I can remove the files from my iPad? File sharing only allows for add and save but it doesn't appear to allow for deletion of files.

Thanks

Tom
