This makes so much sense, I can’t believe nobody thought of it sooner:
Project Infinite will enable users to seamlessly and securely access all their Dropbox files from the desktop, regardless of how much space they have available on their hard drives. Everything in the company’s Dropbox that you’re given access to, whether it’s stored locally or in the cloud, will show up in Dropbox on your desktop. If it’s synced locally, you’ll see the familiar green checkmark, while everything else will have a new cloud icon.
In hindsight, it is inconvenient to have to hop over to the web interface to get the full power of Dropbox. This is a step in fixing that. All your Dropbox files show up in Finder or Windows Explorer, even if they’re not really on your device. When you want a file, you just double click on it, and it will download and open.
This showed up on the Dropbox Business Bog, and the discussion focused on company usage, so I’m guess it will roll out business plans first. I’m good with that, as I have a business plan, but I’d love it if it made its way to personal accounts as well.
