Filester is the best free advanced file manager WordPress plugin.
Accessing WordPress directory files and folders requires either your hosting service’s cPanel file manager or a File Transfer Protocol (FTP) client. Those methods could be troublesome when you have to switch between many different WordPress websites.
Typically, a WordPress admin has to manage not only their portfolio and personal blogs but also their clients’ websites.
That’s where Filester comes in. It helps you manage every WordPress configuration file right on the admin dashboard. Whether you need to troubleshoot an error, run a CSS tweak, or simply move your files, the smart context menu of Filester has you covered.
