Filtering folder names with Get-ChildItem

I have written a very simple script to grab a list of folders like below. My question is : I want to export an output like my desired output.

Does anyone here have any information that would help me out?

My script :

Get-ChildItem -Path "D:\GENERAL" -Recurse -Directory -Depth 5 |
    Select-Object FullName |
    Export-Csv c:\tmp\out.csv -NoTypeInformation -Encoding UTF8

My output :

"FullName"
"D:\GENERAL\IT"
"D:\GENERAL\SOFTWARE"

My desired output :

"FullName"
"D:\GENERAL"
"D:\GENERAL\IT"
"D:\GENERAL\SOFTWARE"

To include the root folder in the output, add a (non-recursive) call to Get-Item. Wrap both commands in a scriptblock {…}, so you are able to process their output uniformly. The scriptblock is called using the call operator &. It can be treated like a single command, which enables us to pipe its output to other commands.

$path = "D:\GENERAL"
& {
    Get-Item -Path $path
    Get-ChildItem -Path $path -Recurse -Directory -Depth 5
} |
    Select-Object FullName |
    Export-Csv c:\tmp\out.csv -NoTypeInformation -Encoding UTF8

An alternative way that avoids the $path variable:

"D:\GENERAL" | ForEach-Object {
    Get-Item -Path $_
    Get-ChildItem -Path $_ -Recurse -Directory -Depth 5
} |
    Select-Object FullName |
    Export-Csv c:\tmp\out.csv -NoTypeInformation -Encoding UTF8

Here we are piping the path as input to ForEach-Object which becomes available as $_, the current pipeline object, within ForEach-Object's process script block.
