Today the SharePoint Team at Microsoft announced that a standalone SkyDrive Pro client is available to download for Windows machines. The Pro edition of SkyDrive allows users to easily save, sync, share, and collaborate on documents in SharePoint. It is worth noting that the new client, is only compatible with SharePoint 2013 servers and Office 365.
SkyDrive Pro was pre-bundled (although not functional for all users until now) with Office 365 Pro Plus, Office 365 Small Business Premium, and Office Professional Plus 2013. If you have any of the aforementioned Office suites installed on your PC, there is no need to download SkyDrive Pro separately.
