Is there a way to remove settings from a previous software version

I have a WPF application that makes use of the Settings mechanism. Each time I deploy a version of my application, I notice I get a new folder for the version. These folders look something like this:

C:\Users\(username)\AppData\Local\Company_Name\MyApplication.WPF.exe_Url_1vtxeuikkx5nbggwlqbrhxrkiruybflb\0.4.27.0
C:\Users\(username)\AppData\Local\Company_Name\MyApplication.WPF.exe_Url_1vtxeuikkx5nbggwlqbrhxrkiruybflb\0.4.28.0
C:\Users\(username)\AppData\Local\Company_Name\MyApplication.WPF.exe_Url_1vtxeuikkx5nbggwlqbrhxrkiruybflb\0.4.29.0

While I realise that these folders are small, I would like to be able to remove old versions of the user settings, as these will never be needed again. Ideally, I would like to remove the entire folder. Is there a way to achieve this?

What I have tried:

So far I haven't tried anything because I can't think of anything to try.

I was considering trying a brute-force approach, by getting the folder where the application stores its data and using the functions in System.IO to manually clean-up.

I don't know but I would guess writing code is your best option. Unless you are creating a package install and some installers have an option to remove previous versions.

I ended up simply bypassing the Microsoft settings system. I know rolling your own solution is often considered bad-form but it so often seems to be the case that out-of-the-box solutions don't work the way you want and are not easy to modify. I even ended up writing a load of code to modify the functionality of the wonderful NLog recently because it simply would not do what I needed it to do.
