If your Operation System is Windows VISTA or Windows 7 follow UAC dialog will popup .
It need to click 'Yes' button to confirm so that can launch ExtremeCopy.
Because some folders must need administrator privilege to copy to or move out , so ExtremeCopy have to elevate it's privilege to assure copy fine during copy process.
This UAC confirm just popup only once before restart or close your Operation System, and then it will not popup again if you copy any files/folders to any folders.
Even thought elevate to administrator privilege but we promise that ExtremeCopy will not do any malice to your machine or get any informations about you without your permit. It also include future version
