Google Drive stores Microsoft Word, Excel, and PowerPoint files much like any file server. Microsoft Office files, however, no longer need to be stored on your local computer, server, or even on Microsoft's OneDrive.
As a result, people still open and edit Word, Excel, and PowerPoint documents after a move to Google Apps. Mass conversion of highly formatted documents, complex spreadsheets, or animated presentations may not always be practical. Many organizations that rely on Google Apps also use Microsoft Office applications.
