How to remove empty folders using PowerShell

To remove empty folders from your D: drive, use following command:

$folders = gci d:\ -r | ? PSIsContainer -eq $True
$folders.Count
$emptyfolders = $folders | ? {$_.GetDirectories().Count -eq 0 -and $_.GetFiles().Count -eq 0}
$emptyfolders.Count
$emptyfolders | select * | ogv
$emptyfolders | Remove-Item

It has some room for improvement (i had to do multiple passes, because after cleaning up some other folders appeared empty (before they contained only empty folders inside it). And dont use it on C: drive, there might be useful empty folders.
