File upload on root domain

I need to upload a TXT file to the root domain of a site. Is there a way to do that?

Here is my public share link: LINK

Not on Webflow, no. You can create a subdomain and host that file elsewhere at the root level. Something like if that helps.

Also check and see if redirect will work for your use case.
If so, you can upload the TXT file to assets, and then setup a redirect that points to it.
