So my job is to take the homepage (or maybe I should say "homesite" because it encompasses a few interrelated pages) and drag this onto its own Apache server. The problem I'm having right now is being able to weed out jumbled/bundled files (such as folders of js, css, and other files that i cant even identify) and knowing what is necessary to keep the homesite running.

I'm new to this stuff (I'm an intern) so feel free to ask questions if I'm leaving vital information out.

What I'm asking of you guys here is basically any pointers or tips you may be able to give me in order to get the job done. I could use some advice from people with a little more experience in web development.

btw: This question may appear as though I have not completed any prior research and that is, for the most part, true. But the problem is I really am not sure how to research this. If you guys could throw me some keywords to play with that would really be helpful. Thanks!
