Show Folders FileCount Filtered For Folders with 500 Files

Find just 500 file folders... (and skip looking in the node_modules directory)

dir -dir -rec | ? { $_.FullName -notlike "*node_modules*" } | % { $name = $_.FullName; dir "$($_.FullName)" -file | measure | ? { $_.count -gt 500} | % { write-host "$name $($_.count)" -f darkcyan } }

Or if written out in full:

Get-ChildItem -dir -rec | 
Where-Object { 
    $_.FullName -notlike "*node_modules*"\
} |
    ForEach-Object { 
        $name = $_.FullName;
        Get-ChildItem "$($_.FullName)" -file | 
            Measure-Object |
            Where-Object {
                $_.count -gt 500
            } |
            ForEach-Object {
                write-host "$name $($_.count)" -f darkcyan
            }
}

Show files in all folders, but exclude node_modules, .git and .obj folders....

 Get-ChildItem -dir -rec |
	Where-Object {
		$_.FullName -notlike "*node_modules*" -and
		$_.FullName -notlike "*\obj" -and
		$_.FullName -notlike "*\obj\*" -and
		$_.FullName -notlike "*\.git" -and
		$_.FullName -notlike "*\.git\*"
	} | % { Get-ChildItem "$($_.FullName)" *.* -file }

Just get some files, not all folders

Get-ChildItem -dir -Exclude *node_modules*, .git, obj | % FullName |
    % { write-host "$_" -f yellow;
        Get-ChildItem $_ -file | 
        % { write-host $_ -f blue; } }
