Also be aware that unlike the desktop program, SkyDrive in Windows 8.1 relies on symbolic links to point to cloud-stored files in File Explorer, even though everything appears to be saved locally at first glance. This "smart files" functionality can save a lot of space on tablets and other storage-restricted devices, but if you'd like to keep local copies of your stuff, right-click the SkyDrive icon in File Explorer and select Make available offline.
You can also right-click individual files and folders and choose to make them online-only or available offline.
Still worth the upgrade
Don't let these little omissions dissuade you: Windows 8.1 is superior to Windows 8 in virtually every way. It represents a much less jarring version of Microsoft's grand vision of a cross-platform future—though it still won't win over folks whose lips instinctively curl at the merest mention of the word "Metro."
