In a quest for more openness, Google has just introduced Google Drive plug-in for Microsoft Office users. With this in place, users can now directly save documents to their Google Drive account.
For instance, someone using Office for Windows can now open their Word, Excel and PowerPoint documents stored in Drive, make changes and save them back to Drive once they’re done. This is also convenient for sharing files among groups or for syncing across devices.
You can download the plugin HERE.
