A useful first step is to stop using Finder. Instead perform the required operations from the terminal. When you don't yet know how, Google it. The first couple of useful commands are ls: list files (lots of options); cd: change directory; cp:copy; mv:move -- aka rename; vi:edit text file; file: what type of file is it? ... etc. If that's too daunting, then still have Finder open, but try to match the operations with above and more.
