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

Something like this works for me. The script delete empty folders and folders containing only folder (no files, no hidden files).

$items = gci -LiteralPath E:\ -Directory -Recurse
$dirs = [System.Collections.Generic.HashSet[string]]::new([string[]]($items |% FullName))
for (;;) {
    $remove = $dirs |? { (gci -LiteralPath $_ -Force).Count -eq 0 }
    if ($remove) {
        $remove | rm
        $dirs.ExceptWith( [string[]]$remove )
    }
    else {
        break
    }
}
