UpDir for any path

[Jewtus]

Simple command but I couldn't find it when I went looking on the boards. I got the idea while looking for a way to get scriptdir's parent folder (Took the command from HERE)

Func GetParent($sDir,$nUpDirs=0)
    local $sUpdir
    For $z=0 to $nUpDirs
        $sUpdir=$sUpdir&"..\"
    Next
    $Parent_DIR = _PathFull($sDir&$sUpdir)
    Return $Parent_DIR
EndFunc

Give it a path and the number of folders up you want to go and it returns the path. Requires #include <File.au3>

[Exit]

Or

$sDir = @AppDataDir



$sMsg = $sDir & @LF

$sMsg &= _GetParentDir($sDir) & @LF
$sMsg &= _GetParentDir($sDir, 2) & @LF

MsgBox(262144, Default, $sMsg, 0)

Func _GetParentDir($sDir, $nUpDirs = 1)
    Return StringLeft($sDir, StringInStr($sDir, "\", 0, $nUpDirs * -1) - 1)
EndFunc   ;==>_GetParentDir

now, it's up to the RegEx freaks to show a RegEx solution.

You should have error checking.

You should also use something like StringSplit, to tell how many up folders there are, and also cater for the drive letter.

_PathSplit is probably the better way to go too, and determining whether the original path is to a folder or file.

Its called updir, so it can be safely assumed we are dealing with directories and not files

I suggest you think about that.

Directories or folders, also have Up Directories, so the path given could be either a file or folder path.
