Custom file in staticfiles directory not accesible

I can access all files in tutor/data/openedx/staticfiles from browser with url localhost:8000/static/, but when I put a custom image or custom font there, then it is not accesible, so what is the reason? How can I make my custom files accessible?
And I am in developer mode, running watchthemes.

In development mode, static assets are not served from the tutor/data/openedx/staticfiles directory, but from the various static folders inside the edx-platform repo. I’d rather delve into the details, as they are going to change in the near future.

Thanks, It’s ok if it available in production mode, and if there’s any help I can provide, let me know.
