1. Click on the Windows Explorer icon in the start bar.
2. Right click the “Computer” tab, click “Map network drive”.
3. In the resulting pop-up window, select a drive letter (in this case, Y:), and enter the full network address (i.e. example.appc.upenn.edu). Be sure to check the “Reconnect at sign-in” checkbox. Then click Finish.
The folder should be mapped automatically, but if it’s not, use your login credentials for authentication.
