General FAQ

How do I log in?

Go to https://filetransfer.colorado.edu and log in using your CU Login Name, e.g. buffalor, and IdentiKey password.

You can also log in using your primary email address. To find your primary email address:

  1. Log in to https://cuidm.colorado.edu with your CU Login Name and IdentiKey password.
  2. Click Manage My Email Addresses
  3. The address listed under the Campus Published Email Address is the address to use.
How does the recipient log in to retrieve the file?

Off-campus users that do not have an IdentiKey must first receive an invitation to retrieve a file. When they enter the address in their browser to retrieve the file, they will be prompted to create an account. They can then use that account to download the file again, if needed. That account expires after 14 days.

How long is my file available for download by the person I sent it to?

Once the recipient has been notified that a file is ready to download, they have 14 days to retrieve it. It can be downloaded as many times as is necessary in the 14 days. In the event that the File Transfer service’s software must be rolled back to an earlier version, files may not be preserved.

What is Accellion?

Accellion is the company that provides the service functionality. The server and all of the data is located on-campus.

What is a fingerprint?

The file fingerprint is used to verify that the file that you sent or received was not corrupted or changed during transfer. It is based on the contents of the file and not the name of the file or the date it was created or changed. Click here to read more information about file fingerprint.
