How to recursively remove all empty folders in PowerShell?

Question

I need to recursively remove all empty folders for a specific folder in PowerShell (checking folder and sub-folder at any level).

At the moment I am using this scrip

Answer 1

$files = Get-ChildItem -Path c:\temp -Recurse -Force | where psiscontainer ; [array]::reverse($files)

[Array]::reverse($files) will reverse your items, so you get the lowest files in hierarchy first. I use this to manipulate filenames that have too long filepaths, before I delete them.
