You can map a drive letter to Teams files, Sharepoint files, or OneDrive folder in Windows 10! This makes it easy to move files in cases where the interface may be otherwise inefficient for some tasks–backing up all the files on a Sharepoint site for example.

First add this URL to trusted sites: https://*.sharepoint.com/

Login to the Office 365 portal and authenticate for your organization in Internet Explorer (Yes, has to be in IE).

Load these pages in Internet Explorer (Again, has to be done in IE substituting your username/domain/teamname/org info–compare the URL in your organization 365 tenent to see how to format.): https://ORG.sharepoint.com/personal/USERNAME_DOMAIN/Documents https://live.sharepoint.DOMAIN/sites/SITENAME/SUB_SITENAME https://ORG.sharepoint.com/sites/TEAMNAME/Shared Documents

For Teams map a drive to: https://ORG.sharepoint.com/sites/TEAMNAME/Shared Documents

For Sharepoint map a drive to: https://live.sharepoint.DOMAIN/sites/SITENAME/SUB_SITENAME

For OneDrive map a drive to: https://ORG.sharepoint.com/personal/USERNAME_DOMAIN_ORG/Documents
