Dropbox has a futuristic vision for how its users will be able to share massive files and have quick access to them on their computers, without their hard drives overflowing.

For the time being, Dropbox is the only cloud storage provider that lets you see online files using your computer’s file browser.

Dropbox won’t say when it plans to include Project Infinite in the publicly available version of its desktop applications, or even which customers it will be available to when it does launch.
