Delete all contents in a folder

I noticed that the RmDir command only works if the folder is empty. I need to set up an uninstaller that deletes all files in a certain folder because things that end up in this folder are user defined and I can't calculate everything that ends up in it. 🙁

Very easy to do when you read the manual. (Also look at Delete).

How do you use wildcards?

Like you use them in any other application. * is anything, ? is any single character.
