C-file organization

I finally received my C-file, Its a link that I had to download a zip file. I briefly have gone through it and have found a few thing that caught my eye. But my question is : before I start this task of trying to put some kind of sense into how it was organized……….or not.

Any suggestion would help so I organize it in a way that makes it a little easier to find possible issues. I was thinking of setting it up like the old detectives would with a full wall with push pins and string…many many pages going back to the 80’s… I have my work cut out and honestly thinking of putting it into chronological order…..
