Moving in the opposite direction, there’s a new way to work locally and act globally, or more accurately, in the cloud, with the newly-released-to-everyone Google Cloud Connect for Microsoft Office. This service allows two or more to work on the same Microsoft Office file (2003 forward / Windows PCs only) and back it up using Google Docs.
Cloud Connect adds a toolbar to the Microsoft Office interface. With that toolbar, you can give Microsoft Office the same online capabilities as Google Docs. You also can give Google Docs meaningful offline capability.
The killer feature is sharing and simultaneous editing of Word, PowerPoint, and Excel files from within office, but via the great Google cloud. Synced files are continuously backed up and fitted out with a unique Web address for sharing. Even offline edits make it up - Google Cloud Connect will sync those changes the next time you log onto the Web.
Don’t worry if you get too crazy with the edits – Cloud Connect stores previous versions and you can roll back to earlier versions if you want. When there are two or more edits to the same section at the same time, the user can choose which version to keep.
All you need is a free plug-in and a Google account. Google Cloud Connect works on Windows XP, Vista, and Windows 7. However, sadly enough, it doesn’t work with Microsoft Office for Mac. Not sure if there is any hope for a Mac version in the future.
You can download here Google Cloud Connect onto your capable machine running the eligible Microsoft Office versions. And get cloud backup and collaboration within the Google ecosystem for free.
