Filezilla is an FTP (file transfer protocol) utility for uploading or
download files to website. Filezilla is another great Open Source program that is fast and efficient. FTP is a convenient utility for managing files on a website. It normally uses ports 20 and 21 for commands and data but by using its passive mode you can bypass firewalls that block or filter those ports. Passive mode works by having the client side assign new FTP ports to the server for both commands and data transfer that side steps the firewall. When you first start Filezilla you see a window that has you local computer files listed on the left and the website files on the right. Just highlight the folders on the website by right clicking and then select the folders on your computer by selecting and right clicking and select upload. The files and folders will immediately start to transfer to the website. A report provides some details concerning the transfer process. We also have some FTP Filezilla YouTube videos providing a demo and some details.
