title_body: How to read .DOC with Kindle paperwhite It's said that only a few types of files are supported on Kindle including .azw, .azw1, .txt, .mobi, and .prc. However some of my .DOC files are still shown on Kindle, while other .DOC files are not.
  Wondering why? 
  Are there some specifications to adjust to make it happen?
upvoted_answer: You are mistaken. If you upload a .doc to Amazon via Personal Documents Service, it should convert automatically -- no problem!

  Now it may not look great, but generally you are mainly interested in the text.
