Click-and-drag a resource or resource folder icon to move it into a new position in either the List or Grid views. This will work on "native" resources that were created in the current class, but it will not work on dynamic file folders, or resources shared from another class.
On a mobile device or tablet, you can use the "up" and "down" arrows to reorder your content.
Archived resources will be moved to the bottom of the Resources page and partially grayed-out. Archived resources are visible to admins, but not to group members. Even after a resource has been archived, it can still be shared to other classes.
