AFS at Stanford

After January 14, 2020, Microsoft will no longer provide security updates or support for computers running Windows 7. All Windows 7 computers used for Stanford activities should be upgraded to Windows 10 by January 2020. Learn more about upgrading to Windows 10 by January 2020.

Because this website uses an older two-step authentication method, when you download the software you might not see the updated version of the two-step authentication screens.

AFS at Stanford is used to mount mount AFS directories to your Windows Explorer or Mac desktop, to use similarly to the way you would work with other folders. You can access your own AFS space, or space in other user, group, class, and department directories, provided you have been granted the necessary permissions. 

AFS at Stanford provides an alternative to SFTP clients, such as SecureFX (for Windows) or Fetch (for Macs), for those who frequently access files in AFS.

  • Kerberos for Windows must be installed prior to installing AFS at Stanford for Windows


  • Supported Operating Systems:  OS X 10.7 and later
