Ignoring folder with large number of directories - powershell

Question

I have written a PowerShell script that traverses over a directory and captures a list of folder names that are nested inside. It uses the following loop to achieve this
Get-ChildItem -Path $targetPath -Directory -Recurse |
Select-Object -ExpandProperty "Fullname" |
ForEach-Object {
#log folder name
}
However I want the script to skip directories that have a configured number of folders nested inside.
For example in the following example I do not want to capture the 'Folder C' because it has more than 3 folders nested.
Folder A/Folder AA
Folder A/Folder AB
Folder B/Folder BA
Folder C/Folder CA #DO NOT CAPTURE
Folder C/Folder CB #DO NOT CAPTURE
Folder C/Folder CC #DO NOT CAPTURE
Folder C/Folder CD #DO NOT CAPTURE
Folder D
So I would like my output of the script to be
Folder A/Folder AA
Folder A/Folder AB
Folder B/Folder BA
Folder D
How can I edit my script to achieve this?

If you just want to exclude folders on the top level you could do something like this:
Get-ChildItem -Path $targetPath -Directory | Where-Object {
(Get-ChildItem $_.FullName -Directory).Count -le 3
} | ForEach-Object {
Get-ChildItem $_.FullName -Directory -Recurse
} | Select-Object -Expand Fullname
If you want to exclude any (sub)folder that contains more than 3 subfolders you'll have to implement the recursion yourself. Get-ChildItem does not provide that kind of filtering mechanism.
