I can't delete files in Workspace


I am in Colt Steele’s Web Developer Bootcamp through Udemy. I have a Workspace called webdevbootcamp.

There are subfolders called Client and Node Modules. I need to right click and delete them, but there’s no option to do so. I’ve already deleted and re-created the workspace. I also tried to download, edit the workspace, and upload it without the subfolders, but to no avail.

Is there a workaround? I was told in a Udemy forum that about the only other thing I could try is to work in a local environment, but that would defeat my ability to follow the instructor in Cloud 9 and complicate a lot of my work.
