You can't choose other folders to sync, but you can redirect certain folders such as your Desktop and folders in libraries to your SkyDrive folder. You can also add subfolders from your SkyDrive folder to libraries to make them easier to work with in File Explorer. For example, if you have a folder of vacation photos on SkyDrive, you can include it in the Pictures library in Windows 7 or Windows 8. To learn how to do this, see Include folders in a library.
