Every time I open Finder it open in a small windows I want it open in a bigger window how can I do this?
The way to set up a "default" Finder window is indeed a bit obscure: first you'll open a new Finder window, and then without clicking on any file or folder arrange the window to your needs (resize, position, define view, show/hide sidebar, etc.) and close it again immediately. Every new window should now use this new setup as a default.
