I need help organizing my files.

Pretty much when I've finished a first draft and copy paste it and work on it futher keeping the old one intact incase I need to go over it

I use new folders and mark them with say A1 and A2 to keep them seprate but the hard part is I have to trasfer a lot of things (Like my notes and outlines) to this new folder and things tend to get a bit mixed up while I'm editing say the character notes or setting note and others.

Is there a better way to do this?

Question on my process futher are welcome
