Work Folders bring the functionality of Dropbox to corporate servers. Install this role on a Windows Server 2012 R2 system, and you get a fully functional, secure file replication service. The initial release will support only Windows 8.1 clients. Support for Windows 7 and iPad devices is promised for the future, with Android clients further down the list. Like Dropbox, Work Folders will keep copies of files on both the server and the client, performing sync operations whenever the client establishes a connection with the server.
