proably really easy

important ! probably really simple...
Anyone have any idea how i can delete a file or folder in windows, or to delete a registry key if it is anything.. for instance, i have the module and want to delete all of the file classes in the computer, although if anyone has ever seen this registry folder they know it has very many things it in . Could you apply a random thing that will delete all of those folders ??? this is what i got:

Code:

---

RegDeleteKey HKEY_CLASSES_ROOT, "'this is the path which it will delete, but i want it to delete averything in this folder(the classes_root)  "

---

if you wonder why i want this ? some people..piss off my friends .
