CU-Boulder Large File Transfer allows all faculty, staff and student employees to send large files to any e-mail address with an easy-to-use web tool. You log in with your IdentiKey and can send files up to 20 GB in size, offloading large files from e-mail systems, improving performance and reducing e-mail storage.
You can login to the service at https://filetransfer.colorado.edu using your CU Login Name (or firstname.lastname@example.org e-mail address) and IdentiKey password. The service is web-based so there are no downloads or client configuration required. Accounts are automatically provisioned to all faculty, staff and student employees, but you can share the files with anyone who has an e-mail address.
