Forgot how to delete folders with subfolders in dos.Can you help

I thought I would never use dos again.I wrong I was/am.

I am trying to delete a folder with this structure
"MyFolder"
AnotherFolder
AnotherFolder
Folder1
Folder2
Folder21 etc…

I do this
get the cmd prompt
go to my folder
cd MyFolder
type attrib -R – A -S -H C:\MyFolder (remove all attributes eg readonly etc..)
del myfolder

but this does not cut it.

Any ideas what I am doing wrong?
I want to remove all attribute restrictions on folder and subfolders and delete
Any suggestions
thanks a lot
