WHAT IS THE USE OF FILEZILLA ?
and why i have to set it up with my server
and why i must put the ip and pw in server.ini file ?

its an FTP server... for crest (guild icons)
its not a requirement, you can skip it if you dont mind not having guild icons

used to connect to you sever and upload/download files

For storing and serve Guild icons function :D
