There is a limit to the size of files that can be transmitted over the University email system. Files larger than 20 MB cannot be sent as e-mail attachments. An alternative is to upload your file to a secure web file hosting service such as GOEsend
GOEsend allows files up to 2 GB to be hosted for a period of time you can select; from 1 day to one week. After uploading your file you will be given a web address that you can send to those you wish to download it. This service is run by University of Kent, and is available to send or receive files to staff and students of Greenwich. Your file will be deleted from the GOEsend servers once the time limit has expired.
Email notifications from the GOEsend system may time a few hours to come through, so please don't wait until the last minute to send your data
