The new Dropbox

Building on our history of helping organize your content, the new Dropbox brings cloud content together with traditional files so you can keep it all in one place. The new Dropbox and Slack integration helps bridge the gap between content and communication, letting you collaborate seamlessly on shared content. All Dropbox users can opt in to the new desktop app through our early access program, and we’re rolling out the other features over the next few weeks.
