# How can I find all the Grand-Parent directories where a file resides

I would like to find all the grand-parent directories where a file exists using PowerShell but can't think of how to do it. I figured I need to do something like this:

``````Get-ChildItem -Filter MyApp.exe -Recurse | format-table Directory
``````

Suppose I have the file in the following places:

``````C:\test\AppA\201608114\MyApp.exe
C:\test\AppA\20160812a\MyApp.exe
C:\test\AppA\201608136\MyApp.exe
C:\test\AppB\201607115\MyApp.exe
C:\test\AppB\201607104\MyApp.exe
C:\test\OtherApps\AppC\201606234\MyApp.exe
``````

So in the above example I would like Powershell to output:

``````C:\test\AppA
C:\test\AppB
C:\test\OtherApps\AppC
``````

Is there a way to accomplish this in Powershell. Almost at the point of just writing a Perl/Python script for this but figured I'd give PowerShell a shot at it first

``````Get-ChildItem -Filter MyApp.exe -Recurse | ForEach-Object {
