Shell – Powershell script not deleting child items

powershell

I am getting an error when running a PowerShell script. It is stating

The item at Microsoft.Powershell.Core\FileSystem::\[path to directory] has children and the Recurse parameter was not specified.

In my PowerShell script I do have it specified. Is it in the wrong location? 

# Add CmdletBinding to support -Verbose and -WhatIf 
[CmdletBinding(SupportsShouldProcess=$True)]
param
(
# Mandatory parameter including a test that the folder exists       
[Parameter(Mandatory=$true)]
[ValidateScript({Test-Path $_ -PathType 'Container'})] 
[string] 
$Path,

# Optional parameter with a default of 60
[int] 
$Age = 60   
)

# Identify the items, and loop around each one
Get-ChildItem -Path $Path -Recurse -Force | where {$_.lastWriteTime -lt (Get-Date).addDays(-$Age)} | ForEach-Object {

# display what is happening 
Write-Verbose "Deleting $_ [$($_.lastWriteTime)]"

# delete the item (whatif will do a dry run)
$_ | Remove-Item
}

The problem is here:

$_ | Remove-Item

While you've specified -Recurse and -Force on Get-ChildItem, that doesn't affect the later Remove-Item invocation. On Get-ChildItem, -Force just includes hidden and system items.

Normally, this would suppress the confirmation, and for me it does:

$_ | Remove-Item -Recurse -Force

Given that it's apparently still asking you for confirmation, it seems you have a $ConfirmPreference other than High. To get around that, you can add -Confirm:$false to the removal line to say "definitely do not ask for confirmation", or you can add this line further up in your cmdlet:

$ConfirmPreference = 'High'
