Return to Revisions

This one provides a little more info than Mike's (again, replace web URL and list name). I'm outputting to a text file because you said there's 32000 folders, I doubt you want to scroll through 32000 lines of window buffer:

$TestSPSnapin = get-pssnapin | ? { $_.Name -eq "Microsoft.SharePoint.Powershell"} 
if($TestSPSnapin -eq $null){
    add-pssnapin -Name Microsoft.SharePoint.Powershell #-ErrorAction SilentlyContinue
    # SilentlyContinue is only good for interactive console where you're sure of each command you're running. Otherwise, the script should block execution on snapin load failure.
}

function CheckFolderContents ($folder)
{
    $folderContent = "Folder at URL " + $folder.Url + " has " + $folder.Files.Count + " files and " + $folder.SubFolders.Count + " subfolders.`n"
    Add-Content C:\FolderContents.txt $folderContent
    
    foreach($subfolder in $folder.SubFolders)
    {
        if ($subfolder.item -ne $null) # the default "Forms" folder has a null Item, and we don't need to include the default "Forms" folder as part of this
        {
            CheckFolderContents $subfolder
        }
    }
}
