If you want to display the progress of a file copy, how about:
code:
$iSourceSize = Getfilesize($sSourceFile)
$iDestinationSize=0
Run '%comspec% /c copy $sSourceFile $sDestinationFile >>c:\mcafee.txt'
$iDestinationSize = GetFileSize($sDestinationFile)
While $iDestinationSize < $iSourceSize
	Chr(13) "Copying - please wait: $iDestinationSize/$iSourceSize (" $iDestinationSize * 100 / $iSourceSize "%)"
	Sleep 1
	$iDestinationSize = GetFileSize($sDestinationFile)
Loop
Chr(13) "                                                      " Chr(13)
Given $sSourceFile and $sDesinationFile it'll display a rising file count and a percentage.
