OpenAFS for Stanford

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.

Stanford OpenAFS 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. 

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

System requirements


  • Supported Operating Systems: Windows 7 and later
  • Kerberos for Windows must be installed prior to installing OpenAFS for Windows


  • Supported Operating Systems:  OS X 10.7 and later


  • Faculty, staff, and students with a full-service SUNet ID


If OpenAFS stops working after a Windows update, uninstall OpenAFS and then reinstall it.
