Instructors can allow all students to upload and edit file to a selected folder in Resources. Instructors must first create the folder. (See How do I create folders?)
Select the Resources tool from the Tool Menu of your site.
To grant uploading permission to all students, to the right of the folder, from the Actions drop-down menu, select Edit Folder Permissions.
This displays the folder permissions dialog box.
In the student column, select Create resources, Edit own resources and Delete own resources, then click Save.
