Amazon’s Kindle eReaders and tablets are designed to let you read books, magazines, and newspapers from the Kindle Store. But an added perk has long been that customers can use a “Send to Kindle” feature to read text, HTML, Word, and PDF documents, clips of web pages, and even DRM-free Kindle-compatible eBooks.
Amazon even provides users with 5GB of cloud storage space for Personal Documents, letting you synchronize your document collection across multiple devices.
Now Amazon’s making it a bit easier to manage your documents.
The company is merging Send-to-Kindle with Amazon Cloud Drive. That means you can now find a list of all Personal Documents you’ve uploaded at amazon.com/clouddrive, letting you sort your files, delete files in bulk, download files, or move, rename, or share them.
New documents will also be saved in their original format, so if you upload a TXT or Microsoft Word document, you’ll be able to access the original file from any device that can access Cloud Drive.
If you want to keep using amazon.com/myk to access your documents, you can do that — but the new Cloud Drive option makes it much easier to find the documents you’re looking for and much easier to delete or move a large group of files at once, for instance.
Incidentally, Amazon gives 5GB of free Cloud Drive space to anyone. Kindle owners get another 5GB of free space for Personal Documents. So now that Amazon is merging the services, Kindle owners get 10GB of cloud storage for free.
Unfortunately there are still a few things you can’t do with Personal Documents.  Although personal documents are available on Kindle devices, iOS devices, and Android devices, you still can’t read any Send-to-Kindle content using Amazon’s browser-based Kindle Cloud Reader or the Kindle app for Windows 8 which is available from the Windows Store.
