Automatic confirmation of deletion in powershell

The default is: no prompt.

You can enable it with -Confirm or disable it with -Confirm:$false

However, it will still prompt, when the target:

• is a directory
• and it is not empty
• and the -Recurse parameter is not specified.

-Force is required to also remove hidden and read-only items etc.

To sum it up:

Remove-Item -Recurse -Force -Confirm:$false

...should cover all scenarios.

Try using the -Force parameter on Remove-Item.

Add -confirm:$false to suppress confirmation.
