Again, I don't know what "FTP to a site" mean
...And apparently you have no desire to research it.
If you go ahead and click on the "FTP" link - either one; it can be the one in my last response, or the one that's present in the instructions I directed you to - it will get you started on your way to understanding how to use ftp. If that fails, try a Google search. something like:
"how to" ftp - or - "what is ftp"
You might venture over to the support site where you have your website hosted, and log in to search the FAQ and support documents for information on how to use the ftp account your host provides for you.
Or, alternatively, you can use the file manger located in your hosts control panel - also mentioned in the opening paragraph of information found at the FTP link
Your ftp credentials are available from your host. You'll need to contact them to find out what they are, or to get hep with setting them up.
They can also provide you with information and assistance on how to use the tools they have provided for you when you purchased an account. Most hosts often have videos and - or - tutorials to help you along with using their built in file manager, how to manage your ftp accounts, and how to use the MySQL administration tools that are available to you.
