Each site's Resources has a quota. That is, the limit to the amount of Resource storage space (in megabytes [MB] or gigabytes [GB]) allowed by the institution. Users can see how much storage space is currently being used in Resources and view the allowed quota.
Select the Resources tool from the Tool Menu of your site.
This displays the Resources Quota page.
The amount of storage space currently being used and the site's quota will be displayed.
