+Storage

Keep your favorite photos and videos safe in the cloud and save storage in your smartphone!
The +Storage logs in your Dropbox account and it makes a smart reading of the photos and videos in your device. Through a simple and user friendly interface, you may select the files that you want to keep in your device and the ones you want to store without wasting free storage.
The +Storage will automatically upload your selected files to Dropbox and remove safely all the local copies of the file, providing free storage to new files and apps.

If you are a Samsung user you don’t even have to bother about a Dropbox account.
Samsung gives you 50GB of storage for two years for free. You just have to follow the instructions at http://www.dropbox.com/gs
