File too big

I had the problem of not being able to parse the file due to the cannot find the js preloader. I added a preloader, included the DOM. It uploaded this time but the error message is that the file is too big.

I have the latest version of edge suite, cc.

Does anybody know which file is too big? The OAM file? Any suggestions on what to slim down?
