Last week @beningus, also a Dutch PowerShell interested IT Pro, contacted me for some assistance troubleshooting a script.
The purpose of that script was to list the directories of, for example, the homedirs on a fileserver in order to find the “big spenders” among the users. For this, we’ve written the following function:

function Get-FolderLength 
{ 
  # Usage: Get-FolderLength.ps1 D:\Homedirs 
  param ( [Parameter(Mandatory=$true)] [String]$Path ) 
  $FileSystemObject = New-Object -com  Scripting.FileSystemObject 
  $folders = (Get-Childitem $path | ? {$_.Attributes -eq "Directory"}) 
  foreach ($folder in $folders) 
  { 
    $folder | Add-Member -MemberType NoteProperty -Name "SizeMB" –Value(($FileSystemObject.GetFolder($folder.FullName).Size) / 1MB) 
  } 
  $folders | sort -Property SizeMB -Descending | select fullname,@{n=’Size MB’;e={"{0:N2}" –f $_.SizeMB}} 
}
