How to redirect to all pages except one?

Question

URL Handling

I have a redirect from without www to with www

via htaccess

RewriteEngine On
RewriteCond %{HTTP_HOST} ^site.com
RewriteRule (.*) www.site.com/$1 [R=301,L]

How to make it redirect all pages, except for one, on this one page I have a text file that I need to confirm that the site is mine (the site with WWW is not on my hosting, but on a free server where I cannot upload files, and I use my hosting for manage dns records, but I can also upload data there, but if I upload a confirmation txt file, it will redirect to www and the system will not see the file).

it was necessary to add
RewriteCond %{REQUEST_URI} !^/file\.txt$
