Retrieving all IIS Directories using PowerShell

To tidy up the applications on the IIS of my development PC, I wanted to find out which IIS application (and their virtual directories) point to which physical paths.

Starting out with this SO answer and some help from MSDN I quickly assembled this PS solution for the task:

$dummy = [System.Reflection.Assembly]::LoadFrom(
    "c:\windows\System32\InetSrv\Microsoft.Web.Administration.dll")

$srvmgr = new-object Microsoft.Web.Administration.ServerManager

write-Output  ("site`tstate`tapp`tvirtdir`tphys.path")

foreach($site in $srvmgr.Sites | Sort-Object Name ) {
  foreach($app in $site.Applications | Sort-Object Path ) {
    foreach($virt in $app.VirtualDirectories | Sort-Object Path ) {

      write-Output  ($site.Name + "`t" + $site.State + "`t" + 
        $app.Path + "`t" + $virt.Path + "`t" + $virt.PhysicalPath)

    }
  }
}

This piece of code generates a tab-separated list of physical paths referenced by IIS sites, applications, and virtual directories. The application’s physical path is contained in a virtual directory with Path=”/”.

Note that the script must be “run as administrator” from the PS prompt or the PowerShell ISE.
