Suppress automatic confirmation of deletion in powershell - powershell

Question

I am trying to write a silent script that deletes files older than 14 days and removes empty folders. The part that deletes files work fine, but the part that deletes folders is popping up a confirmation window no matter what I do to suppress it. Here's my code:
$date=(get-date).AddDays(-14)
$ConfirmPreference="None"
$DebugPreference="SilentlyContinue"
$ErrorActionPreference="SilentlyContinue"
$ProgressPreference="SilentlyContinue"
$VerbosePreference="SilentlyContinue"
$WarningPreference="SilentlyContinue"
$OutputEncoding=[console]::OutputEncoding
function FullNuke ([string] $strPath) {
Get-ChildItem -Path $strPath -Recurse -Force | Where-Object {!$_.PSIsContainer -and $_.LastAccessTime -lt $date} | Remove-Item -Force
#The line below is the one that triggers the confirmation
Get-ChildItem -Path $strPath -Recurse -Force | Where-Object {$_.PSIsContainer -and #(Get-ChildItem -LiteralPath $_.FullName -Recurse -Force | Where-Object {!$_.PSIsContainer}).Length -eq 0} | Remove-Item -Force
}
Most of the answers I have found say to add -Recurse to my final Remove-Item command, but that would be the opposite of what I want. If the folder is empty, I want it removed. If it is not empty, I do not want it removed. I'm not sure why non-empty folders are even being caught in the first place.
UPDATE
After much frustration, I discovered that the second line was processing items in reverse order, thus requiring confirmation. It was also not properly identifying empty folders, which also triggered confirmation. I ended up using the following function.
function FullNuke ([string] $strPath) {
Get-ChildItem -Path $strPath -Recurse -Force | Where-Object {!$_.PSIsContainer} | Where-Object {$_.LastAccessTime -lt $date} | Remove-Item -Force
Get-ChildItem -Path $strPath -Recurse -Force | Where-Object {$_.PSIsContainer} | Where-Object {#(Get-ChildItem -LiteralPath $_.FullName -Recurse -Force).Length -eq 0} | Remove-Item -Force
}
I put it here because while it is a solution (it erases files and folders to my satisfaction), it is not an answer to my posted question.

Answer 1

Remove -Force from first Get-ChildItem and add -Recurse and -Confirm:$false.
This will work:
Get-ChildItem -Path $strPath -Recurse |
Where-Object {$_.PSIsContainer -and
#(Get-ChildItem -LiteralPath $_.FullName -Recurse -Force |
Where-Object {!$_.PSIsContainer}).Length -eq 0} |
Remove-Item -Force -Recurse -Confirm:$false

Answer 2

If you are using v3 or higher powershell client you can use the -directory and -file switches for Get-ChildItem and use this:
function FullNuke ([string] $strPath) {
Get-ChildItem -Path $strPath -Recurse -Force -File | Where-Object {$_.LastAccessTime -lt $date} | Remove-Item -Force
Get-ChildItem -Path $strPath -Recurse -Force -Directory | Where-Object {(gci $_.FullName -File -Recurse -Force).count -eq 0} | Remove-Item -Force -Recurse
}
Yes, I added -Recurse to the folder removal because with my testing no folders with any files in them were being passed to that point, and if it is a folder with nothing but empty folders in it then they all need to go anyway right?
