G Suite already offer way to collaborate with teams and clients while on the go as it allows users to securely store and share files in the cloud. Now, it has added more file types, including Microsoft Office files, PDFs and images, so users can comment directly on these files without having to convert them into Docs, Sheets or Slides.
In the Drive preview pane even if a person isn’t using G Suite, can also “comment, assign tasks, or mention coworkers,” so people in your team can reply back without need to open other tools to complete tasks. With this update, let’s say, a coworker opens a file using Word will now be able to see comment in the file and can reply right from there.
In this screenshot you can see new Drive preview pane with Word, PowerPoint, Excel and PDF files:
Instead, open Microsoft Office files, like Word, Excel and PowerPoint, in Drive preview and give feedback in comments then get back to work. Also, by using a Outlook Drive plug-in you can easily insert files stored in Drive to an Outlook email and save incoming attachments to Drive from Outlook.
Another ability today, enable collaboration on Excel files, as well as other Microsoft files—all within Google Drive.
See the screen shot below of collaboration on Excel files:
Lastly, you can choose to edit Microsoft files without converting them fully using Office Compatibility Mode (OCM).
Of course, you can still convert Microsoft Office files into Docs, Sheets or Slides—simply, click File -> Download as and select the file type.
