On the Mac, you've become accustomed to software that's not just powerful, but elegant too. Armed with the belief that file-transfer should be no exception, we made Flow. Flow brings the best of the Mac to your server's files and folders. Put simply, Flow makes working remotely every bit as intuitive and natural as working locally with the Finder.
