title_body: Send to kindle - store in specific folder When using "send to kindle" feature (e.g. through Readability), is there any way to put the files on Kindle into some folder, not into main directory?
  
  Usually I send some articles to read them later, but then they end up in main folder and there's a big mess. If they could be stored under some folder, e.g. "articles" that would be much cleaner. Any way to do so?
upvoted_answer: The equivalent in Kindle to folders is collections. Usually you can create this on the ebook reader yourself. 
  
  This Kindle help document https://www.amazon.com/gp/help/customer/display.html?nodeId=201733490 indicates that there is a cloud component to collections on later devices, but I don't know what this means for kindle apps.  
  
  For the Android Kindle app's main screen, when you keep holding down on the ebook title,a  + option will appear  which allows you to add to collections.
