We cannot recommend moodle for submissions of files of this size, filesubmission data is stored in the moodle database which is both very expensive and limited. This is in addition to potentially causing problems for the server when uploading and downloading files of this size.
Our recommendation is that studentsshare their files with you using OneDrive, this is a Microsoft service provided for students by Unitec, unlike moodle it is intended for file storage and sharing.
Here you have a number of options about how to share your file, the easiest (but least secure) is to click “CopyLink” and paste that into an email to your lecturer.
Alternatively click on the drop down and untick the box that says allow editing, then Apply, then “CopyLink”.
There are also options for sharing for specific people, which is recommended for more security. But I will let you explore those options once you gain familiarity with sharing using the above steps.
