If you want to delete an entire folder from Classwork.com, it's simple. Here's how:

On your Classwork.com Activities page, click the checkbox to the left of the folder you'd like to delete. A yellow menu bar will appear.

Click on the trash can icon labeled "Delete."

Once you do this, you'll see a "Delete Selected Items" warning pop up. Make sure you're absolutely sure that you want to delete the selected folder and ALL of its contents. Once you're sure, click "Confirm Delete."

You can follow these same steps to delete a subfolder you've placed inside a main folder. 

If you don't want to delete your folder but simply want to move it, see Moving Folders.

While you can't recover entire folders, you can recover the individual activities that were inside the folders. If you need assistance with that, see Recovering a Deleted Activity.
