If you have both the SkyDrive desktop app and Office 2013 installed on a PC, you can quickly access all the Office files that you've stored on your SkyDrive. When you change an Office file, only those specific changes are synced to SkyDrive, so your Office files sync faster. And you can work on Office files simultaneously with other people on different devices without creating conflicts. To optimize SkyDrive for use with Office 2013, follow these steps:
Right-click the
SkyDrive icon (

) in the notification area, at the far right of the taskbar. (You might need to click
Show hidden icons first to see the icon.) Then click
Settings.
On the Settings tab, under General, select Use Office to sync files faster and work on files with other people at the same time, and then click OK.
