@ian10 ,
we keep to 500MB to encourage colleagues to think carefully about compressing images, files etc which is a matter of student experience (some students are in remote locations with slow wifi, or ar paying for data / storage).
Additionally there are now serious global concerns about environmental impacts of could based data and energy needs of server farms - hence we need to be better users of data infrastructure and storage if the planet is to survive, and efficiency is important.
Out of 800 deliveries, we only have a handful of courses that genuinely require over 500MB, which we tweak individually, and keep video on Yuja or Teams.
Note that student limits are completely seperate to course and teacher limits, and copied content does not increase quota use.
