Microsoft has released a standalone SkyDrive pro client for Windows. If you are not aware of of SkyDrive Pro, read it below.
SkyDrive Pro is a place to keep your work documents and other files. You can think of SkyDrive Pro as your SkyDrive for business. When you store your files on SkyDrive Pro, only you can see them, but you can easily share them with co-workers and access them from your mobile devices. Your files are safely kept in the cloud with SharePoint Online or on your company’s SharePoint Server 2013 servers, depending on what your company has set up.
The standalone SkyDrive Pro sync client allows users of SharePoint 2013 and SharePoint Online in Office 365 to sync their personal SkyDrive Pro and any SharePoint 2013 or Office 365 team site document libraries to their local machine for access to important content on and offline. The SkyDrive Pro client can be installed side-by-side with previous versions of Office (Office 2010, Office 2007, etc)
