File Explorer - Open Folder in another app

[Renderer]

Hi guys, I want to ask you a question. It might be a stupid question. It has nothing to do with AutoIT but I think this forum is the last place where I can get an answer, since I have looked for one all over the internet. The question is about opening Folders and File Explorer.  As far as I know when we open a Folder it is rendered in the File Explorer (explorer.exe).  I want to know if there is a way to make a folder open with another program and all the details of that folder to be rendered in that program instead of File Explorer. What I mean is this: When I double click a folder, it should avoid opening in File Explorer, but instead another App (that I build)  opens that folder and renders the content and all the other details. If you have any idea about how this could be done, please share it. It would be very helpful to me.

There are a number of custom file manager/file explorer examples on the forum.
