I wanted to know how to use filezilla that comes with XAMPP, i started it as a services but how do i get a graphical interface? do i have to install filezilla server or client explicitly ?
You can use any FTP client to connect to the Filezilla server that XAMPP includes, all you simply need to do is set the domain as localhost or 127.0.0.1 and use the username and password it tells you to use which normally is root with no password or root and password.
The FileZilla that comes with XAMPP is the server part. When that service is running it allows you to use any FTP client to connect to that server to transfer files. There is no graphical interface for an FTP server. The interface is provided by the FTP client.
