Trim (or go up) one level of directory tree in powershell variable -

say have variable $source = "c:\temp\one\two\three" , want set $destination equal $destination = "c:\temp\one\two" programmatically, how might it?

the best idea i've had trim that, there better way?

perhaps like

$source = "c:\temp\one\two\three" $dest = "..$source" 

getting parent directoryinfo object, lee suggests, work. alternately, if prefer use more powershellesque commands opposed direct .net framework calls, can use powershell's built-in split-path cmdlet this:

$source      = "c:\temp\one\two\three"  $destination = split-path -path $source -parent  # $destination string value "c:\temp\one\two"
