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

I have adapted the script of RichardHowells. It doesn't delete the folder if there is a thumbs.db.

##############
# Parameters #
##############
param(
    $Chemin = "" ,  # Path to clean
    $log = ""       # Logs path
)




###########
# Process #
###########


if (($Chemin -eq "") -or ($log-eq "") ){

    Write-Error 'Parametres non reseignes - utiliser la syntaxe : -Chemin "Argument"  -log "argument 2" ' -Verbose 
    Exit
}



#loging 
$date = get-date -format g
Write-Output "begining of cleaning folder : $chemin at $date" >> $log
Write-Output "------------------------------------------------------------------------------------------------------------" >> $log

    define a script block that will remove empty folders under a root folder, 
    using tail-recursion to ensure that it only walks the folder tree once. 
    -Force is used to be able to process hidden files/folders as well.

$tailRecursion = {
    param(
        $Path
    )
    foreach ($childDirectory in Get-ChildItem -Force -LiteralPath $Path -Directory) {
        & $tailRecursion -Path $childDirectory.FullName
    }
    $currentChildren = Get-ChildItem -Force -LiteralPath $Path
    Write-Output $childDirectory.FullName



    <# Suppression des fichiers Thumbs.db #>
    Foreach ( $file in $currentchildren )
    {
        if ($file.name -notmatch "Thumbs.db"){break}
        if ($file.name -match "Thumbs.db"){
            Remove-item -force -LiteralPath $file.FullName}

    }



    $currentChildren = Get-ChildItem -Force -LiteralPath $Path
    $isEmpty = $currentChildren -eq $null
    if ($isEmpty) {
        $date = get-date -format g
        Write-Output "Removing empty folder at path '${Path}'.  $date" >> $log
        Remove-Item -Force -LiteralPath $Path
    }
}

# Invocation of the script block
& $tailRecursion -Path $Chemin

#loging 
$date = get-date -format g
Write-Output "End of cleaning folder : $chemin at $date" >> $log
Write-Output "------------------------------------------------------------------------------------------------------------" >> $log
