Microsoft ties together its visual changes and features with a new
set of built-in app improvements, centered more than ever around
SkyDrive. Microsoft’s cloud-based storage system really powers
Windows 8.1 this time around. The sync engine is built directly
in, and Microsoft has made some smart improvements to the way that
files sync to Windows 8.1 PCs. Instead of pulling down the entire
SkyDrive storage to a local PC, it loads icons, and just enough
information required to identify the file. When you open the file,
it downloads it on the spot. You can set folders and files to
download fully so they’re available offline, or just set an entire
SkyDrive instance to remain offline on the PC.
The end result is that all your settings, files, and apps are
stored in SkyDrive. This makes it incredibly easy to log in to any
other Windows 8.1 PC and start loading apps and documents as if it
was your own machine. Like so many things about Windows 8.1, sync
seems like a logical update, but it’s one of the most significant
improvements to Windows 8.1.
Sounds like a great feature. Effectively, system-level Dropbox.
