Question How to delete a subdomain without deleting the main domain?

[inado1]

In plesk, In my domain list,

I have

fr.mydomain.com which points to /domain.com (a wordpress installation aware of subdomain)

and

mydomain.com which points to /domain.com (same folder path)

I have disabled the subdomain in plesk because I have moved the website from fr.domain.com to domain.com/fr/ and I don't need redirect.

How should I do to delete the subdomain?

I can click "remove subdomain" but I am concerned that it would also delete the main root folder that i use for my main domain

If I click on "remove subdomain" will it also delete the main root folder that already exist?
