Remove old backup files with PowerShell

Note: script looks at when file was last modified and also removes if any file exists in sub folders recursively.

$path="C:\app"
$NumDaysToRetain=3
$extension ="*.bak"

Get-ChildItem -Path $path -Filter $extension  -Recurse  | 
Where-Object{ $_.lastwritetime -lt (get-date).adddays(-$NumDaysToRetain)}  | 
ForEach-Object { Remove-item $_.FullName; write-host "File" $_.FullName "deleted"}
