I am currently creating my first wordpress website, and I have two pages already created - a About page and a Contact page. The locations of these are example.com/ and example.com/contact/. I would like to create some more pages but in a sub folder of the domain, e.g. example.com/folder1/red and example.com/folder2/blue. I would also want to save posts (not pages) in a subfolder 'blog' such as example.com/blog/post1. Would someone please tell me how to do this? Thank you in advance!
