Is the projects folder on claude similar to creating a folder via the terminal? I know this is elementary but before I knew about Claude code, I created a project to be a "sherpa/ghostwriter" asking me introspective questions, trained on my writing style, writing in general, and we went chapter by chapter speaking out the book. Would it work better in code? I know the folders on the computer allow AI to maintain the memory but is that different in how projects on claude work?
