ifile is a simple web-based file manager for AFS filestore.


When you login (via Cosign) to our ifile server you'll be shown your home directory. You can then download and upload files, as well as copy, rename, delete, and so on.

You cannot edit files directly via ifile. To edit a file you should:

  • Download the file via ifile to whatever computer/device you are using,
  • Edit the file using the tools on that device,
  • Upload the modified file using ifile.

Though you start off in your home directory, you can navigate to any /afs/ file path for which you have AFS permissions, including other AFS cells, by using the 'Change' button near the top of the page. A common use of this is to access Informatics AFS group areas.


The ifile service is based on filedrawers, a University of Michigan open source project which they run for their users as MFile. We've taken their code and adapted it for our use. Their online help is more or less applicable to our version though, obviously, for please read

Because the underlying code comes from the US, dates displayed are in the month-day-year format.

From November 2021, will only be accessible from the University networks. To access ifile from outside of the University, you will need to use either the University or School VPN service.


There is currently a bug which limits file uploads to ifile to about 3MB.
