Look up _PathSplit() in the help file:

#Include <File.au3>

Global $avInputs[3] = ["N:\QUAKE3\QUAKE3.EXE", "N:\QUAKE3\abc\QUAKE3.EXE", "C:\My Dir\My Sub Dir\My File.ext"]
Global $sDir, $sDrive, $sExt, $sFName

For $n = 0 to UBound($avInputs) - 1
    _PathSplit($avInputs[$n], $sDrive, $sDir, $sFName, $sExt)
    $sOutput = StringTrimRight($sDrive & $sDir, 1); Remove trailing "\"
    ConsoleWrite($n & ": _PathSplit() = " & $sOutput & @LF)
Next

Edit: Unless you want the clean, efficient, one-line answer (but who wants that?)... then you go with Authenticity's.
