How do I install Google Drive File Stream to access folders on Windows or Mac?
Do I need an @wsfnet.org account to use Team Drives on my phone or Chromebook?
No. See the flowchart.
Can I move files and folders from My Drive into Team Drives?
Yes and no. You can move files, but not folders. You can create folders in Team Drives and select multiple files and move those all at once — just not folders themselves.
