If you need to send large files (over 50 MB for Windows users and 10 MB for Mac users), DEIC (former Forskningsnettet) offers a service which allows you to upload your files to a server. The receiver will get a 'ticket' which he or she can use to download the files. You log on with your WAYF login.
Please notice that FileSender is not an AU program. Please contact DEIC if you have any questions.
