Google Drive is a file storage and sync service, introduced to the public by Google, on April 24, 2012. Google Drive is an extension to Google Docs once activated and replaces the URL docs.google.com with drive.google.com. It gives a free storage of 5GB. One interesting feature of the service is smart tagging, which allows you to tag items stored on your drive. So if you’ve uploaded a picture of the Golden Gate Bridge to your drive, the next time you perform a search for the bridge, your photo will show up along with other results. It also uses image recognition. Its also possible to share the file. Check out the video for more information.
