I'm really tired of iTunes adding an iTunesMetadata.plist file to my original EPUB files every time I test said EPUB files on my iPad or iPhone through iTunes. To add insult to injury, every time you do it, it causes an error in ePubCheck—since the EPUB file now contains a non-manifested file—thus making the file invalid for uploading to your iBookstore.
Could you please quit it?
Feel the same way? Feel free to copy the above letter and post it in your own name to Apple's Feedback page for iTunes. Perhaps if enough of us speak up, they'll listen.
