Viivo

Viivo lets you sync and share all of your data from multiple cloud services, allowing you to access all of your files at once. It could save you money and time, which will be more than worth the monthly fee for power users. While it could support more services, its features can't be matched by any one cloud storage program alone.

This program opens up multiple cloud storage accounts in one place. While it has support for most cloud storage programs, including Dropbox, Google Drive, Box, and SkyDrive, it misses a few big names like iCloud and Amazon. It will only let you use Dropbox if you pay a monthly subscription fee, as well. Without the fee, you can still find Android, iPhone, and Mac apps so you can access your stuff from multiple devices. If you do decide to get the monthly subscription, you unlock the ability to compress your files so you can use your cloud storage space wisely. Setting up Viivo can be a bit of a pain, since you have to enter your e-mail address several times before you even get to add your accounts with the other services. It's not a particularly small download, either.

Paying the small fee for access to all of your accounts can save you from having to buy more storage with any one service. That alone makes Viivo a neat option. It'd be nice if more of its features were available in the free version of the software, though.
