Sometimes

Answer 1

If you type Get-Help Remove-Item -Detailed you'll see:

Example 4: Delete files in subfolders recursively
PS C:\>Get-ChildItem * -Include *.csv -Recurse | Remove-Item

This command deletes all of the CSV files in the current folder and all subfolder recursively.

Because the Recurse parameter in Remove-Item has a known issue, the command in this example uses Get-ChildItem to get the desired files, and then uses the pipeline operator to pass them to Remove-Item .

Do what specification recommends:

if(Test-Path -Path $OUT) 
{ 
    Get-ChildItem $OUT -Recurse | Remove-Item
}
New-Item -ItemType directory -Path $OUT
