I recently found some useful information on how to use an FTP client for WordPress on this article. It turns out that FTP allows you to quickly and securely manage files in your site's format. With an FTP client like FileZilla, you can easily upload, modify, and delete files, as well as resolve WordPress access issues if you can't log into the admin area. An FTP client especially comes in handy for restoring your site or performing backups. It helps you bypass hosting restrictions and gives you full control over your files.
