  to readable on a Kindle e-reader, 7th generation?  I've mounted and unmounted the Kindle multiple times.  The file is there, it's the correct size, it's readable from Calibre -- not sure what else I can do.
  
  There it is, on the Kindle.  But, not getting picked up.  Other mobi files are recognized and readable.  But not this one.
  
  why?
  
  
  
  this is in the context of:
  
  The Kindle Personal Document Service can convert and deliver the following types of documents:
  Microsoft Word (.doc, .docx)
  Rich Text Format (.rtf)
  HTML (.htm, .html)
  Text (.txt) documents
  Archived documents (zip , x-zip) and compressed archived documents
  Mobi book
  
  
  Even after compressing to .zip it's too large (at least for gmail).  To re-iterate, the e-books is perfectly readable from calibre and so I don't see that it should be a problem with the file being corrupt or unreadable.
  
  I don't seem to be alone with this general problem of dealing with absurdly large e-book files on the Kindle...

  Perhaps convert the EPUB to PDF, slice into tranches, then re-convert back to EPUB?  Sounds like an invitation for everything to go wrong, but might work..
  
  Oddly, the mobi size seems quite out of whack versus the EPUB format:
upvoted_answer: Usually a .mobi file actually includes a couple copies of the book in different formats. Is the .mobi file much larger (like, multiple times) than the epub file? This is the giveaway. The KindleStrip plugin (http://www.mobileread.com/forums/showthread.php?t=96903) might help you remove that excess content to bring the file down to a manageable size.
