Remove WP Super Cache plugin & all files from FTP

Hi, I'm an intermediate DIVI WP builder but don't like / fully understand FTP. I think that WP Super Cache is affecting my some of my webpages from caching correctly. I'd like someone to go into my hosting account and remove all WP Super cache files and remove the WP Super cache plugin. Obviously, I expect you to back up the site and then make the changes. You must know about caching issues and WP Super Cache uninstalling.
