The Google Drive for Desktop sync tool creates a folder or drive on your computer that acts like a local folder.  This allows you to edit files using software on your computer but stores it in Google Drive cloud storage.  This is great to use if you want files like PowerPoint, Autocad, PDFs, Images, etc, to open in their native application and not in  a browser.

For computer managed by Stony Brook that restrict downloading software, you can get Google Drive for Desktop from the Kace Self Service Portal.  See General Instructions and search for the software  Google Drive. 

For your computer where you are the administrator, you can download Google Drive for Desktop by going to drive.google.com > Settings > Get Drive for Desktop
