Instructors can allow all students to upload and edit files to a selected folder in Resources. Instructors must first create the folder. (See How do I create folders?)
Go to Resources.
Select the Resources tool from the Tool Menu of your site.
Select Actions, and then select Edit Folder Permissions.
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.
Modify student permissions, and then click Save.
In the student column, select Create resources, Edit own resources, and Delete own resources, and then select Save.
This allows the students to upload and edit content in the selected folder. Students will have an "Add" section added to their Actions button displayed next to the folder.
