I like the article.

and yes yes... you can do it easier with SQL statements like Jeff says... but what I like about the article is that is uses a very simple problem to teach how to solve it with powershell.

In other words... I don't like the article because it shows me how to delete old back files, but I like it because it's a very simple case of how to build a function, and use mandatory field and check the input, something that I didn't know and that I'm trying to learn.

Good work!
