Today, the company is upgrading the feature with a new version. It now allows for two-way transfers between a Mac or PC and the iOS and Android apps, not just one-way exhanges from phone to computer. And it’s no longer just for photos: You can use a phone to send videos, contacts or any file stored on Dropbox to a computer, and can send any file on the computer to the phone. It’s nearly as simple as the previous photo-centric version, but a whole lot more versatile.
