Instructors can create group folders in Resources that are only displayed to students assigned to that group. Instructors must first create the site groups. (See How do I create groups?)
Go to Resources.
Select the Resources tool from the site Tool Menu.
Select Actions, then Create Folders.
To create a group folder, to the right of the root folder, from the Add section of the Actions drop-down menu, select Create Folders.
This displays the Create Folders page.
Enter name and add details.
Enter a name for the folder, then select Add details for this item.
This exposes the folder details.
Enter item details, then create folder.
Under Availability and Access, select Display this folder and its contents to selected groups, select the group name, then click Create Folders Now.
