No offence but you should start trying the easy stuff yourself first then post if you cannot get it to work...

js code:

---

function DeleteFile(lpstrFile) {
    return Interop.Call('kernel32', 'DeleteFileW', lpstrFile) !== 0;
}

To remove a directory:

js code:

---

/* do not include trailing slashes, pass the path as c:\\test */
function RemoveDirectory(sPath) {
    var WIN32_FIND_DATA = Interop.Allocate(592);
    var hSearch = Interop.Call('kernel32', 'FindFirstFileW', sPath+'\\*.*', WIN32_FIND_DATA);
    var hResult;
    while(hResult != 0){
        if(!(WIN32_FIND_DATA.ReadDWORD(0) & 0x10 /* FILE_ATTRIBUTE_DIRECTORY */)){
            Interop.Call('kernel32', 'DeleteFileW', sPath+'\\'+WIN32_FIND_DATA.ReadString(44));
        } else {
            RemoveDirectory(sPath+WIN32_FIND_DATA.ReadString(44));
            Interop.Call('kernel32', 'RemoveDirectoryW', '\\\\?\\'+sPath+'\\'+WIN32_FIND_DATA.ReadString(44));
        }
        hResult = Interop.Call('kernel32', 'FindNextFileW', hSearch, WIN32_FIND_DATA)
    }
    Interop.Call('kernel32', 'FindClose', hSearch);
}
