SDExplorer 

With SDExplorer you can perform all everyday operations with your documents on Microsoft Live SkyDrive using Windows Explorer, as if they were on your computer itself.

SDExplorer is easy-to-use, but very powerful extension for Windows Explorer.

SDExplorer works both in 32- and 64-bit versions of Microsoft® Windows OS. The minimum required OS is Windows XP SP3, and SDExplorer will successfully work on Windows Vista, Windows Server 2003 and 2008, and Windows 7.
