You can split it at the backslashes  and take the next-to-last one with negative array indexing to get just the grandparent directory name     scriptpath -split       -2    You have to double the backslash to escape it in the regex   To get the entire path     path -split       0     path -split       count -2   -join       And  looking at the parameters for split-path  it takes the path as pipeline input  so    rootpath    scriptpath   split-path -parent   split-path -parent

Version for a directory  get-item is your friendly helping hand here     get-item  scriptPath   parent parent   If you Want the string only   get-item  scriptPath   parent parent FullName   Version for a file  If  scriptPath points to a file then you have to call Directory property on it first  so the call would look like this   get-item  scriptPath  Directory Parent Parent FullName   Remarks This will only work if  scriptPath exists  Otherwise you have to use Split-Path cmdlet

To extrapolate a bit on the other answers  in as Beginner-friendly a way as possible     String objects that point to valid paths can be converted to DirectoryInfo FileInfo objects via functions like Get-Item and Get-ChildItem   Parent can only be used on a DirectoryInfo object   Directory converts FileInfo object to a DirectoryInfo object  and will return null if used on any other type  even another DirectoryInfo object    DirectoryName converts a FileInfo object to a String object  and will return null if used on any other type  even another String object    FullName converts a DirectoryInfo FileInfo object to a String object  and will return null if used on any other type  even another DirectoryInfo FileInfo object     Check the object type with the GetType Method to see what you re working with   scriptPath GetType    Lastly  a quick tip that helps with making one-liners  Get-Item has the gi alias and Get-ChildItem has the gci alias
