Selecting files through Explorer

Thanks for helping because I am really quite new at VBA. I am trying to build an interface for a main code which I have already completed.

My code reads a number of txt files (which is presently specified within the code). It would make more sense to open a form with a couple of dialogue boxes and let the user browse through the Explorer directory tree and select the specific files. This interface would capture the exact file path and name for further processing in my main code. I have drawn a pic to further explain what I mean.

Does anyone have a code to share or is able to point me in the right direction?

Thanks.

I have sorted it out already. Thanks.
