Windows 8.1 includes a new feature for corporate workers called Work Folders. Work Folders is a Windows Server 2012 R2 feature for file servers. In the new trend of Bring Your Own Device (BYOD) to work, corporate workers need to access work files on their personal PCs - files which are stored on corporate PCs. The personal PC or device may not be a part of the corporate network. Work Folders allows synchronizing work files on PCs inside the corporate network with your personal computers.
