Upload the verification file to the root level of your website

So, i have to create email addresses for the domain and i am trying to verify my domain. For some reason i cant use DNS, so no TXT record and no CNAME. The only way i can do this is by puting a .html file under a folder name to the root level of my website . So, is there a way to do so ? This is what they say.

"Upload the verification file to the root level of your website.

(Eg: http://my-website-name/zoho-domain-verification.html)"

zoho-domain-verification.html is the file name
