FTP server allows file exchange between computers via Client - Server communication protocol. To use the server, there is no need for any additional software, just sign in using a window of Explorer in Windows system. There is an instruction shown below, which allows for quick login and file exchange.
Open a window of Explorer and type in the FTP address, in our case it is:
After typing the address and confirm it with the Enter button, we will be transported to a public part of the server, which only allows us to download files. To be able to send files onto the server, we have to make another step.
Click right mouse button on a window and select option "login as", where it will be possible to type in user name and password:
User name: drukarnia
After log in, we have access to FTP server, on which we can send files using "copy" / "paste" option of Windows system or just by dragging a file on an open window.
After putting files on the server, we ask for an e-mail or telephone contact with information that files were copied on our server.
