access question?

I am going to move my WP from one host to another but on the new host want to put ALL of WP in a folder under the root such that once moved, to access the blog visitors will need to type https://www.somedomain.com/folder rather than what they type now which is https://www.somedoamin.com.

I have read thru this page

https://codex.www.ads-software.com/Giving_WordPress_Its_Own_Directory

my question is about the section called:

“Moving a Root install to its own directory“

Once I have done all the steps will the visitor enter https://www.somedomain.com OR https://www.somedoamin.com/folder to access the blog? I want to ensure they have to enter https://www.somedomain.com/folder but the instructions are unclear as we leave the Site Address (URL) as https://www.somedomain.com ??

Thanks Doug
