I don''t understand your question. Some companies allow their games to be moddable by releasing source code, while other games like diablo 2 require the modders themselves to find a way to mod the game themselves.
Have the exe load the game content from a different folder for the different mod. This is what Quake 2/3 does.

To make your game moddable, just make it easily configurable. Pack a lot of the main variables in your game into a textfile, then when your game runs you can read these variables in.
But if you want your game to have full-blown mods like half-life or quake, you''ll need a scripting system to let the modder do what he wants to do. You have many choices here, but the most popular seems to be: create a parser/vm for a scripting language, or make use of dll files. Each of these choices has a downside: the former will add several months to your development time, and the latter makes the modder use C (or any other system programming language) to make the DLL.
My recommendation would be to embed a pre-existing scripting language into your app because it will save you months of development time, and you can use the same language in future projects.

Keep game engine separate from game logic. Game engine is the executable, and game logic can be compiled in a DLL file. This way you can release source to game logic without exposing the actual game engine technology.
Scripting was the way followed in Unreal but I believe Halflife/Quake use DLL''s. DLL''s are easier for the developer to implant but scripting can often be easier for the public to use.
