How to check if a directory/folder exists on Windows-like systems with Ansible?

I’m going to show you a live demo and some simple Ansible code. I’m Luca Berton and welcome to today’s episode of Ansible Pilot

Ansible check directory exists on Windows-like systems

Let’s talk about the Ansible module win_stat. The full name is ansible.windows.win_stat, which means that is part of the collection of modules specialized to interact with Windows target host. It’s a module pretty stable and out for years. It works in Windows and Windows Server operating systems. It gets information about Windows files. For Linux target use the ansible.builtin.stat module instead.

Parameters & Return Values

Mandatory Parameters

Main Return Values

The only mandatory parameter is “path” which is the filesystem full path of the object to check. The module returns a complex object, the property that is interesting for us is “isdir”. This attribute is “true” if the object is a directory
