ZumoDrive enables you to "supersize" each of your mobile devices without compromising performance or usability. From any ZumoDrive-enabled device, you can continue to open documents as usual from your file manager, play songs in iTunes, and browse photos with your favorite photo software.

ZumoDrive can optimize a device's local capacity by storing some of your files locally on the device and keeping other files in the cloud. ZumoDrive intelligently determines which files to maintain locally based on user activity. As a result, you will usually have all of the content you need even if you are offline.

Hybrid Cloud storage enhances your device's file system to enable files to exist in a "deflated" state. A deflated file appears and acts like a normal file but takes up no storage space. Once accesses, the file is automatically and transparently "inflated" via a stream from the cloud. Even if not locally stored, every file appears as a regular file, giving you seamless access to unlimited capacity even on devices like smart phones and netbooks that have very limited storage.

ZumoDrive keeps your content securely backed up using Amazon's S3 datacenters. Your files are first sent to the ZumoDrive servers using a secure SSL connection. From there, your files are encrypted using military grade AES encryption and sent to S3 where they are stored redundantly in 3 different physical locations.
