  • Hi Salaudeen

    Could you help me with a new requirement. I got the report for each of the file in a library but now how do I get a report of the size of each of the folders in a library?


  • Hi Salaudeen

    Another question please. how do I use this script for the top site and all sub sites under it to call the Function to retrieve detailed Library storage Report for each site.


  • Thanks so much. My mistake. should have see that. It work great now on MOSS 2007. Thanks again.

  • Hi
    I tried to run this script on MOSS 2007 by adding
    [System.Reflection.Assembly]::LoadWithPartialName(“Microsoft.SharePoint”) >null

    And changing this line but got the error. Could you help me resolve the error or i need to find some other property to use.

    $List = $WebURL | Select -ExpandProperty “Lists” | Where-Object{$_.Title -eq $ListName}
    Select-Object : Property “Lists” cannot be found.


    • Hi Salaudeen
      sorry for being such a novice. here my PS

      [System.Reflection.Assembly]::LoadWithPartialName(“Microsoft.SharePoint”) >null
      $url = “https://mosssp/sites/TestbySPAdmin”
      $ListName = “DocumentLibrary”
      Function global:Get-SPWeb($url)
      $site= New-Object Microsoft.SharePoint.SPSite($url)
      if($site -ne $null)
      return $web
      $Web = Get-SPWeb($url)
      $List = $Web.Lists($ListName)

      but i got the error
      Method invocation failed because [Microsoft.SharePoint.SPWeb] doesn’t contain a method named ‘Lists’.
      At line:16 char:19


    • The Line: $List = $Web.Lists($ListName) should be “$List = $Web.Lists[$ListName]”
