FTP stand for file transfer protocol – If you are web developer or learner then this name is familiar with you if not then first of all i am going to introduce about FTP and after that talk about client or server software .
According to wikipedia FTP is defined as
The File Transfer Protocol (FTP) is a standard network protocol used to transfer computer files from one host to another host over a TCP-based network, such as the Internet. FTP is built on a client-server architecture and uses separate control and data connections between the client and the server.
Actually as like name , File transfer protocol , You can understand that this is useful for transfer file . but where? .
Let me clear all figure , Suppose you have purchased Hosting package from bluehost or any web hosting provider then you need to upload files to your server and there are two way for upload file to server.
first is via file explore or file manager in c-panel which is provided by hosting provider and second is file transfer protocol (FTP) so now you are clear about why you need FTP. But you can not upload automatically to server via FTP i.e you need some software which is supporting FTP protocol .
So here i am talking about which is best FTP client or server software for you. some software is paid , some are shareware i.e trail version and some are free software . even many professional developers are using free FTP client software . and that software is FIlezilla .
Yes!! FileZilla is free FTP solution software Filezilla is available for both (Server and Client) . This is Open source software for File transfer protocol work.
