Amazon's Cloud Drive app has been around since June, but it's been missing some fairly basic tools. As in, so basic that it's kind of mind-boggling that they haven't been included thus far. Today's update adds the ability to rename and delete files and folders, which was apparently missing before. That seems like a pretty big omission, but it's been rectified in version 1.2. It's available now on the Google Play Store, and of course, Amazon's own Appstore.
The only other change of note is the ability to swipe to preview both photos and images, a nice little addition that brings some quick functionality to the built-in media viewer. (There's no change to the user interface, which is too bad, because it's pretty Spartan at the moment.) Beyond that, it's pretty much the same app that you are probably familiar with if you're using Amazon's free services or paying for extra storage.
Amazon Cloud Drive offers free unlimited photo storage for Prime subscribers, but to store other types of files including documents and video you'll need to sign up for one of the paid plans starting at $12 a month. If you'd like to add some cool cross-service functionality, remember to try out the new IFTTT channel for Amazon Cloud Drive.
