Redirecting and file storage issue

I use Redirect 301 to redirect my domain1 to a URL. The problem is that I can't access my files in domain1 anymore. Let's consider I have a 1.txt file in public_html of domain1. When I want to download it I should be using domain1.com/1.txt, but it doesn't work anymore because of redirecting stuff. How to have redirecting option and ability to use file storage of the redirected domain ? * I tested wild card option, it doesn't change anything thanks
