Amazon has introduced new functionality for Kindle ereaders and tablets with Cloud Drive. Starting today, all personal documents that you have archived in your Kindle Library will be available to access, delete, organize, and share from your Amazon Cloud Drive. You can see these documents in a new “My Send-to-Kindle Docs” folder on Amazon Cloud Drive alongside all of your saved content, such as photos and personal videos.
The syncing of personal documents is done automatically and requires no management on the users part. Also starting today, new documents that you save to the cloud with Send to Kindle will be kept in their native format (e.g. MS Word, RTF, TXT) so you can access them anywhere from Amazon Cloud Drive.
Amazon recognizes that often their customers use the send to kindle plugins for major web-browsers to send interesting bookmarks or RSS feeds to their device. The company is also keenly aware that most of their users get heavily invested in their ecosystem and have more than one in the household. Being able to sync your documents and user uploaded content into your main account means you can access it on the existing hardware but also the new Amazon Smartphone.
