I have main a folder say E:\donuts and there are hundreds of folders inside it. e.g.

E:\donuts\yellow\
E:\donuts\green\
...
E:\donuts\blue\

I want to create a new folder in each subfolder simply using some DOS command. Something like this.

E:\donuts\yellow\big
E:\donuts\green\big

and so on. How can I achieve this?

Also, would to be possible move the content of each subfolder into the corresponding big folder? For instance all the files and folders in E:\donuts\yellow\ should move to E:\donuts\yellow\big and so on.
