Do file names have any effect on SEO

Do the physical filenames have any effect on SEO?

1. css files
2. html files
3. javascript files
4. image files
5. folder names

Thanks!

Hey hope this helps,

• Naming image files something descriptive is crucial to SEO and helps search engines understand what the image depicts

• HTML/CSS/JavaScript files don't directly affect SEO but do play a
  role in overall performance that in turn affects SEO.

• Folder names and structure often appear in the URL and should be a clean and descriptive, if content is logically organized into folders and subfolders it will help search engines understand the hierarchy and relationship between pages
