AFS is a distributed file system at MIT where each student has a personal locker to store and share files. To access this locker from a laptop, the FTP client Cyberduck can be used to transfer files between the locker and the laptop. Cyberduck allows downloading files from the locker to edit locally and then uploading the edited files back to the locker. Instructions for downloading and using Cyberduck on PC and Mac laptops are provided.
