Error on filezilla & question regarding local install of LIVE site using MAMP

I was advised to download filezilla…
…I get an error code:
Error: Could not read from socket: ECONNRESET – Connection reset by peer
Error: Disconnected from server

Your host would be the best place to get support for getting that working at your specific server.

I’ve exported all of my database’s from my hosting phpmyadmin, currently the file is zipped sitting in my downloads.

I think you mean to be saying you have exported all the tables from your single database. After importing those tables into you local database, you will need this SQL code to update the database to your local URL unless you did that at Settings > General prior to the download:

UPDATE pref_options SET option_value = replace(option_value, 'https://www.olddomain.com', 'https://www.newdomain.com') WHERE option_name = 'home' OR option_name = 'siteurl';
UPDATE pref_posts SET guid = replace(guid, 'https://www.olddomain.com', 'https://www.newdomain.com');
UPDATE pref_posts SET post_content = replace(post_content, 'https://www.olddomain.com', 'https://www.newdomain.com');

* note: Edit ‘pref’ (three places) to your own table_prefix and change ‘https://www.olddomain.com’ and ‘https://www.newdomain.com’ as required (three places each and with no trailing slashes)

My MAMP preferences are set to save the root file to htdocs as suggested.

You should get a default installation of WordPress running before importing anything, and then simply add your tables to the database and edit wp-config.php accordingly while also copying the contents of /wp-content/ into place (or you can do that even beforehand).

My goal is to get this done today!

That could be possible, but it typically takes a bit longer the first time.

Good morning!
Thank you for taking the time to respond to me, super helpful!
I did manage to get there in the end so thank you.
Have a good day.
