Changing the default file explorer?

Hello,
so like most people, I can't stand the default file explorer, and have been using the Resco one (with great success, love it) for over a year now. My question is this, is it possible to change the default file explorer the operating system uses?

When I load a word file (for example) from the Resco explorer, it loads, I close it, I see the default explorer, I close that, I am back in Resco. I have hated this for a very long time, and saw no solutions for it :( .

I changed the fexplore.lnk shortcut in \Windows\ to point to Resco, but that didnt do much, so I changed it back :/ ...

I didn't find anything explorer-related in the registry.

Any ideas how this can be done?
