HTML5 Completed Project

I have played with the HTML5 games for awhile now and I figured out that when you build and package the HTML5 game it creates a folder and then 10 files within this folder it creates.
You open up the HTML5LaunchHelper and that opens up some dos Pop up with a web url. You go to this Web URL in the latest Firefox and then it pulls up those files in a web view.
Then inside Firefox you open the Firefox game document and your game compiles and opens after it compiles:)
Success! But, can I create just one html5 document or do I always need these files for the game to work?
Are there additional Build steps I need to complete in Unreal Engine 4 so I can compile everything into one HTML5 file?
I have a website that I can ship these games to but if it only works with those steps nobody will want to play it.
I need to get the folder and all those files into one HTML5 ready to play document.
Is this Possible?
