Because it’s gotta be super easy to share files

When you store your important files somewhere, you want to have peace of mind that they'll be safe and easy-to-access later. That's why everything in Drive is always encrypted. And why we encourage all of our users to complete a simple Security Checkup every now and then. Of course, this should include file sharing as well — it should be super easy to control who sees what. With this in mind, we're making a number of improvements to Drive today, so you can store your photos and documents safely and get them where they need to go. Get sharing notifications You may have noticed recently that it’s easier to select and share multiple files and folders on iOS and Android — but checking your email may not be the fastest way to find out when something’s been shared with you. So starting today, you’ll receive mobile notifications to alert you immediately when files or folders are shared with you and a single tap can take you right to them.
Request and grant file access Drive lets you quickly grab a link to files and folders so you can share them using other apps, but if you share a link before you’ve granted access, the person you’re sending it to won’t be able to open it. Now, the Drive for Android app lets recipients request access with a single tap. And on Android and iOS, file owners will be notified of the request instantly so they can quickly grant access.
Preview files without a Google Account on Android Until now, you needed a Google Account to view shared files on your Android device. Now, you can do this without a Google Account just like on the web.
Some of the features mentioned are already available. Look for the rest to roll out in the coming week or so. Posted by Alex Vogenthaler, Group Product Manager, Google Drive
